Adorable Mochi Pets

0.16.2 - The dolphin escorts you, and only pulls when you swim

It escorts instead of hunting. In water your Mochi no longer abandons you to chase something across the sea floor - it fights whatever comes within ten blocks of you and leaves the rest. That was two bugs in one: it swam off, and the moment it did you lost Dolphin's Grace and the tow, so you slowed to a crawl in open water for no visible reason. On land or in a boat the normal combat rules still apply.

The tow only works while you are actually swimming - the swim pose, not merely being in water. Standing upright at the surface with the impulse applied made you skim across the top as if you were running on solid ground. Upright: nothing. Switch to swimming: the dolphin pulls.

Dolphin's Grace itself is untouched - the impulse was what made you look like you were running on water, not the effect.
