Capybaras are stuck and just continually rotate forever, unable to swim in oceans. However, when given a 1-block high water pool, it swims incredibly slow and you have to be close to attract it to you.

Spawning capybaras from high heights do not make them take fall damage, so capybaras are invulnerable to fall damage.

(extra note: capybaras should be attackable by owners to be consistent with wolves/cats/etc)

Tested in 1.19.3 CurseForge.
