A purse!! This Kuma has a removable strawberry hat, and underneath it is a zipper to a pouch where you can put stuff in his tummy :)) It fits quite a lot of stuff!  The strap is adjustable and can be removed, with loops it attaches to behind its ears.

This little buddy was bought secondhand, but still has the original BTSSB tag attached!  It's never been worn outside, just kept in storage.  Practically like new!
