Opening Grand Cakes in House

Hello,

so I just opened 54 Grand 4th Birtday Cakes in my house. The guys jumped out, but i cant kill them cuz i cant attack in my house. I havent played in a long time and back then it was possible. So can i contact the support somehow? I didnt know it.

Any help for me?

Cakes have been returned, and birthday bandits should always be enemies with this thursday's update. Don't open them until after that.
