Last weekend I caught a bit of crazy and decided to make a life-size papercraft Bulbasaur. Luckily, we hadn't taken out our recycling for weeks so there were lots of cereal boxes around for me to use.

Actually, a real Bulbasaur is supposed to be around 70cm tall, and this one's a bit under 50cm and looks quite reasonably sized. Bulbasaurs are huge, man.
