very cute!
a couple things you might want to consider though, the stuffy cuddle buddy has plastic eyes and nose that your chin could easily chew off and eat. and stuffies are usually stuffed with that white fluffy stuff, not a good thing for chins to get a hold of. perhaps replace the stuffy with a cuddle buddy made of fleece, stuffed with fleece scraps, that is the same size/shape as Hambelina (very cute name btw!).
also, the hidey house - it's made of plywood. plywood has glues in it, and the types of wood that plywood is made from are never confirmed, so you don't know what kind of wood it is made of. not safe for chins.
