Noah's Ark Play

Y wants to play LEGO Duplo. After he took out all the bricks from storage box (bought from Ikea), he came an idea of asking me to gave him his animal toys to play with.

He started to build a stair with LEGO Duplo bricks and use it as stairs of the storage box (Noah's ark). He arranged the animals in order (not really 2 by 2 since we do not have 2 animals toy for each type of animals) to go into the ark.

I didn't took the end result which all the animals board the 'ark' and they were safe from flood.
