Catbus, or Nekobus/Nekobasu, from My Neighbor Totoro [Tonari no Totoro in japanese]. I watched this movie all the time when I was little, and it was always my favorite. I always loved Catbus.. but the only papercraft I found was a hako-level one, so I made a more detailed version.

Two sizes included.. a 20 cm and a 37 cm model, so you can build whichever you like! Two different 'destination' textures included.. Mei and Shichikokuyama [Hospital the girls' mother is at].
