The Truth About Dossy - S2.E9

There's been a lot of buzz at Dombler Village about a lake beast nicknamed Dossy (a parody of Nessie), so Geo travels there out of curiosity. He encounters a television director named Gerry Romero who is secretly gathering data on the beast. Furthermore, he runs into Rich Dotcom (the partner of UMA Yeti). Gerry is eventually pursued by UMA Plesio and transforms into Plesio Surf, defeating both Yeti Blizzard and Mega Man before retreating.
