The Trap Door Sezon 1 Odcinek 23: Vile Pile

Berk is throwing rubbish down the trap door and Boni is worried about the consequences. Something comes out of the door. Meanwhile Berk is busy creating food. The monster looks like a pile of rubbish and Berk picks a bit of it up thinking it could be suitable for his cooking creation. The monster spits rubbish first at Berk, then at everybody and over everything. Berk tries to stop it spitting by sticking a cooking utensil in its mouth. No longer able to spit, the monster blows up and covers them in gunge.
