|First appearance||Paper Mario (2000)|
Mario and Goombario are greeted by Koover when they initially travel to Koopa Village. He also warns them of the Fuzzies attacking the village, before getting his shell stolen by a Fuzzy. Mario can attack the Fuzzy with his hammer to regain Koover's shell.
Koover partakes in a long chain of letters Mario and Parakarry can optionally deliver by first receiving a letter from Muss T. and sending one of his own to Fishmael, who writes back to him. Koover then has Parakarry give one of his letters to Mr. E, at which his role in the letter relay ends. Earlier in the game, though, Koover also sent a letter to Kooper through the Toad Town Post Office, revealing that the two are good friends.
- "A Koopa Troopa from scenic Koopa Village. He's like the welcome wagon. He seems to be a pretty jolly Koopa Troopa. Just look at his face!"
