Tessie (Tassy) is a character in EarthBound. She is a friendly, long-necked monster which lets Jeff Andonuts and the Bubble Monkey ride on her back to cross Lake Tess in Winters. There is an entire club called the Tessie-Watching Club that are dedicated to finding and seeing Tessie, but ironically, they never seem to notice the few times where Tessie comes out to carry Ness's party on its back.
