Seals are enemies found in Bentley's Outpost in Spyro: Year of the Dragon. They were once trained by Bartholomew to throw snowballs (albeit with poor progress), but then turned on him.
The seals throw snowballs at anyone that approaches. If they are on an unreachable spot, they can be defeated by blowing the snowballs back at the seals with Bentley's spin block. They can also be smashed by Bentley's club if encountered on equal ground.
