Hello! Can you please help me, I’m stuck in this location, Diggy can’t get back in the room to burn the birthday cake because of other characters blocking the entrance. And because of that I can’t finish this level.
I'm guessing you missed a required task in order for them to move. Perhaps the walkthrough video will help: https://forum.pixelfederation.com/diggysadventure/d/169617-diggy-s-6th-birthday-walkthrough-videos/6
If not, then you need to contact tech support: https://portal.pixelfederation.com/en/diggysadventure/support
I have the exact same problem ... how did you solve this, please?
