to do the puzzle peice trapdoor, you must group the pegs into their catagories. i.e. fish, flightless birds, flying, only a few pegs arent in a group. just keep grouping them into 3's until the pegs wont come back out.
thanks to shadow741. i thought it was bad b4 i new u could pick up items and combine them. im stuck again in the frog place or w/e but the game is better than i thought.
