After several weeks of playing with cars and animals, suddenly the blocks were out again. (The Bunnies make these choices themselves!) Jessica and Lexi worked very hard to build special places for the lions and tigers. You probably can't tell in the photo, but this structure is multi-leveled with larger animals up high and the cubs down low.
Just so you know, horizontal block building (like zoos and other enclosures) precedes vertical block building (like towers and castles).
