Last night I put a blue smaller Lego, or I quess it's actually a Megablock in with Lil Pumpkin. At first he was analyzing it from all angles! Then he crept up on it and moved it around some. At one point he was 1/2 out of the water feeling in the holes at the bottom of the lego which were floating towards the top! I am going to find my daughtors smaller legos and put some different colors in to see what he does, and what color he seems to favor. Also, seems like Rugrats are the favorite show at the moment! Whenever Jess has it on, there's Lil P plastered on the tank watching!!
