Scooby-Doo! I Choose You!: Scooby's Night with A Frozen Fright

While "surf fishing", Shaggy catches, of all things, an Ultra Beast frozen in a block of ice, which was lost at sea after sliding off the deck of a ship. The kids take the frozen beast to Oceanland, the local aquarium. When they come back to the aquarium later that night to retrieve Shaggy's fishing pole, they find that the ice has melted and the Ultra Beast is now apparently alive and roaming the grounds.

I do not own Scooby Doo or Pokemon, this is jsut a fanmade merge take on a classic Scooby Doo episode
