Dimensional Travel Event

Idea. Once a year a dimensional Travel Event happens in the summer. Each week a Collab drops to add to the event. Like they could get a alien earth. I could be a exiticing event and being looking forward to a new Collab. We could potentially see new parts of the map added in the event that will stay on the map. We could get a upside down themed biome with a vecna goat skin that can control NPCs like you can do in payday.
