Character from EarthBound by Shigesato Itoi / Nintendo
A friendly lake monster in Winters who ferries Jeff across Lake Tess while an entire club of dedicated watchers somehow fails to notice.
Tessie is a lake monster living in Lake Tess in Winters, clearly inspired by the Loch Ness Monster (a newspaper in-game even confirms they're cousins). An entire organization, the Tessie-Watching Club, is devoted to spotting her, yet they ironically never notice the multiple times Tessie surfaces to carry Ness's party across the lake. Jeff first rides Tessie with the Bubble Monkey when escaping Winters. The party returns later, and Tessie ferries them again. She is gentle, helpful, and apparently invisible to the one group of people trying to find her.
A long-necked plesiosaur-like creature in Lake Tess. Green, gentle, enormous. Surfaces from the water with humps visible above the surface.
