If you have a toy train set that up with little characters on it maybe going around the cake. Mickey Mouse Cupcakes with oreos dipped in chocolate as ears. Listen to Park Music on You Tube Make Mickey Ear birthday party hats by attaching ears cut from black construction paper to regular birthday party hats. Then let the kids decorate them Have a castle back drop Play pin the tale on Mickey
If you REALLY want to do it up BIG make each part of your house a " land" so Main Street has the party hats and pin the tale on Mickey Fantasy Land is the cake and train and maybe cut out some dumbos out of paper hanging from the ceiling for " Flying Dumbo" Adventure Land you could set up a game where the kids have to find different types of animals on a Safari ( either little toy animals or cut out of paper ) and then bring them to you for a prize. Frontier Land/ Liberty Square could have a Haunted House with ghost cut outs and spooky music in one room for the kids to walk thru ( if you want to go all out hang posters of the stretching room pictures from the Haunted Mansion. TommorowLand could have a Buzz Lightyear game where kids try to throw rings on aliens and win prizes.
They are Tigger Tales and they are just marshmellows on a stick with orange melted chocolate and chocolate " stripes". They are a Disneyland thing but they look so FUN!
