For The Entertainer and my four-year old nephew I made activity bags (since they are made with Buzz Lightyear fabric we call them "Buzz Bags")
I completely, totally, unashamedly copied these off a picture I saw on Facebook. I contacted the lady to try to give her credit but haven't heard back from her, when I do I'll update it here. I simply took a sheet of felt and cut fabric to fit it. I added pockets for crayons.
