Munro hurls hunks of meat the size of softballs into a glass walled pool, and Odin pounces into the water, diving for treats with a strange expression that could be taken for excitement, while the crowd shrieks with joy.
"He's actually closing his nostrils and folding back his ears to keep the water from going inside," said Munro.
Odin's trainer left behind a job as a fraud investigator 13 years ago to follow a dream of working with animals. These days he rides an Asian elephant named Taj around the park, and juggles duties between the cat and the dolphin shows.
He also raised Odin's brother who can be seen slurping up underwater horsemeat treats in a similar show in a Six Flags park in New Jersey.
There is a tiger splash lineage in Vallejo. Odin learned his diving from a now 'retired' tiger named Kuma, and has since passed the trick on to a much younger cub named Fedor.
Fedor, though, still lacks Odin's underwater grace.
"That's how Odin was when he first started out," said Munro, still sopping wet from the tank. "He was klutzy, his butt was bobbing around in the air, and his tail hanging out, but now look at him."
