You should look into Henry Lee's
"Aquarium Notes: the octopus or the "devil-fish" of fiction and of fact."
I believe this is the earliest version of the story.
Here it goes:
"CHAPTER V. THE OCTOPUS OUT OF WATER.
Until by the establishment of aquaria opportunities were furnished of observing the habits of the octopus in captivity, very little was known as to the truth or otherwise of the statement that it would sometimes voluntarily leave the water, and ramble on land in search of food. Professor Edward Forbes* says that, in the sudden falls, lasting not very long, of the sea-level, which occur from various causes in the bays of the countries in and around the JEgean, this creature may be met with walking on the exposed shore ; but he thinks it doubtful whether it ever wanders of its own choice above the usual water-mark.
Aristotle affirms that it comes out of the sea and walks in stony places ; and Pliny tells of an enormous polypus (octopus) which at Carteia, in Grenada — an old and important Roman colony, near Gibraltar — used to come out of the sea at night, and carry off or devour salted tunnies from the curing depots on the shore ; and adds that the head of it, when it was at last killed, was found to weigh 7oolb. ^Elian records a similar incident, and describes his monster as crushing in its arms the barrels of salt fish to get at the contents. These old writers seem to have aimed rather at making their histories sensational than at carefully investigating the credibility or the contrary of the highly-coloured reports brought to them. They were, of course, gross exaggerations; but there is a substratum of truth in them ; and in the proceedings of an octopus in the Brighton Aquarium we may recognise the living model of the bold, broad sketches from nature from which the old artists fancifully drew their showy but untruthful pictures.
In May, 1873, it was found that some young lump-fish (Cyclop- terus lumpus, were mysteriously disappearing from one of the tanks. Almost daily there was a fresh and inexplicable vacancy in the gradually diminishing family circle, and morning after morning a handbill might have been issued : — " Missing ! Lost, stolen, or strayed, a young ' lump-sucker,' rather below the middle size, and enormously stout ; had on a bright blue coat, with several rows of buttons on it, and a waistcoat of lighter colour. Whoever will give such information as shall lead to the discovery of the same, or produce satisfactory evidence of his death, will relieve the troubled minds of the curators ! " " What on earth can have become of them?" "Where can they be?" were the questions each attendant asked in vain of another. If they had died they would have been found in the tank, for there were no crabs there that could have eaten them ; they could not have burrowed in the shingle, for it was not deep enough ; and, with their obesity of form, they could no more have leaped out of the tank than Mr. Wardell's fat boy in " Pickwick " could have jumped a five- barred gate. Here was a puzzle ! One by one they were lost to sight, as regularly and unaccountably as pair after pair of Lieu tenant Charles Seaforth's breeches disappeared from his bedroom at Tappington, as related in the " Ingoldsby Legends."
One morning, however, Mr. Lawler, one of the staff, on going to count our young friends, found an interloper amongst them. "Who put this octopus in No. 27 tank?" he inquired of the keepers. " Octopus, sir ? no one ! Well, if he ain't bin and got over out of the next tank ! " And this was just the fact. The marauding rascal had occasionally issued from the water in his tank, and clambered up the rocks, and over the wall into the next one ; there he had helped himself to a young lump-fish, and, having devoured it, returned demurely to his own quarters by the same route, with well-filled stomach and contented mind.
This was not very difficult for him to accomplish, for the partition between the two tanks is only about a foot above the surface of the water. Having accidentally, or otherwise, discovered that there was a preserve of live stock suitable to his palate next door, he paid frequent nocturnal poaching visits to it, and, after clearing up every remnant of his meal, regularly slunk home before day light ; until, like most criminals, becoming careless by frequently escaping detection, he, on the last occasion, indulged at supper- time in an inordinate gorge, and slept under his neighbour's porch, instead of going home to bed.
His return homeward at daybreak was caused by no intelligent fear of his keeper, but by a perfectly natural instinct inherited from his ancestors, namely, that of retiring during the day to his own favourite den or lurking-place, as an ogre is supposed to ensconce himself in his castle or cavern after having satiated his rapacious maw in a successful foray. For it must be remembered that the octopus is nocturnal in its habits, and ordinarily hides itself as much as possible during the day, shrinking from the light, which is apparently disagreeable to it : its wanderings in search of food, therefore, generally take place at night.* * A few days after the publication in Land and Water of my account of this occurrence, the following lines appeared in Fun. They were written by its editor, poor dear Tom Hood, who loved all animals — birds, beasts, and fishes — and delighted in conversing with me about those under my care : (see below)
Although I had once seen the octopus in question crawl out of the water on to the rocks above the surface in the daytime, and had often witnessed his activity during the dark hours, and the surprising rapidity of his progress by crawling or walking, he had not been seen to do all of which he was accused. Every opportunity was, therefore, given to him of continuing his incur sions into his neighbours' compartment, and it was hoped that he would be caught in the act. So acute, however, are these creatures in their perceptions, so quick of sight, and so sensitive to the light of even a distant lantern, that our suspected pirate would not start on a buccaneering expedition whilst anyone was cruising in the building. He seemed to know that he was watched ;
and for about a week remained quietly at home. During that time no more young lump-suckers were missing. Then he again broke bounds, and, moreover, prevailed on one of his class-mates to follow his bad example of going out on the loose.
One night these two individuals left their tank, and started in opposite directions on a voyage of discovery. One went east, the other went west ; and, as if by preconcerted plan, neither was content merely to cross the frontier and visit his nearest neigh bours, but both passed through, or over, one intervening tank, and settled down amongst the tribes beyond. One of them found himself in a Brobdingnag of crabs — a colony of giants too strong to be successfully invaded even by an armada of octopods. If he had arrived at Lilliput instead — a tank inhabited by pigmy crus taceans — he would soon have depopulated it, by clutching in his hateful embrace more victims per diem than ever an unwelcome, foul-mouthed dragon of old demanded as his daily dole of youths and maidens, to satisfy his inconvenient preference for their flesh as his daintiest dish. The other traveller found his way into Lobsterdom, and putting on a bold front, proceeded to attack the chief. The lobster, though evidently alarmed, "showed fight," and the intruder was obliged to retreat, and seek refuge in a cranny of the rock-work. Although the lobster which bore the brunt of the attack was a very large one, I was at the time sur prised that it so decisively vanquished the invader as to save from destruction the other smaller specimens of its kind, which were its companions. For it is an old notion, still generally believed by fishermen, that if an octopus approaches a " pot," or " stalker," in which are lobsters that have been entrapped, they will cast off their claws, and become literally sick from fright.
— THE STRAYING 'TOPUS. A LEGEND OF THE BRIGHTON AQUARIUM.
Have you heard of the Octopus —
'Topus of the feelers eight —
How he left his tank o'po'pus
Lump-fish to disintegrate ?
To the lump-fish tank, as sprightly
As the Brighton, coach, he'd ride ;
For two passengers he nightly
Found convenient room inside.
On his feelers, long and curly,
Homeward then he gently strode ;
And you'd have to get up early
To perceive him on the road.
But it happened Mr. Lawler,
Whom the lump-fish ought to thank,
Caught this very early caller,
" Dropt-in" on his neighbours' tank !
For some weeks the world lump-fishious
Very strangely vanished had ;
— So the visit was suspicious,
And appearances were bad !
Well for him, this brigand larky
Was not brought before J. P.
(Neither clergy, nor squire-archy) -
But to Mr. Henry Lee. Said he,
" Punish on suspicion, Is a thing I never will
— Catch him in the same position ;
Then I'll send him to the mill !
" Treadmill is a wear-and-tear case,
And Octopus would, you see,
Do four men upon a staircase —
Law, how tired the beast would be"
