The Ghost Portal was a portal opening to the Ghost Dimension, where the Ghosts from the Moshis vs Ghosts live. It first appeared on the fourth part of Moshis vs Ghosts. The Portal was created when the Ghost of Dr. Strangeglove's Hand casts a spell to open the Portal to the Ghost Dimension for revenge.
The Portal is oval in shape and resembles a mouth with lips that can be closed as a zip. The Portal is surrounded by four chimera statues with eyebeams that keep the portal open. These chimera statues resemble Twaddle.
When entering Goosebump Manor to collect Ecto Gloops, the mouth remains open and although the chimera statues lack their sunglasses, they do not project beams any longer. For some reason, the mouth has turned vertically.
