Feature description

Polar bears are amazing swimmers, being able to ride a polar bear across bodies of water without sinking would be a nice way to differentiate it more from the summoned horse mount.

How it improves the player experience

I'm not sure how best to describe it, but it would be far more intuitive for a water/ice themed mount to be able to swim with the player on it!

i believe the polar bear can swim. if he cannot, that is a bug

Polar bears cannot swim currently, they just sink to the bottom like a skeleton horse. Would you mind re-opening this issue?

They also drown underwater - definitely no good for water traversal.
