K'nex R2-D2
Sorry it has taken me months on end to publish this but I haven't been to my grandma's house lately(which is about the only place I can publish stuff!). Anyways, this is R2-D2 from the star wars franchise. He has the orange pieces just for the purpose of remaining in the standing position (otherwise he would do the splits!)

He can fly if you have a book of incantations.
