Axolotl model in boats can be off centered

Axolotls have funny models in boats occasionally

so when you put 2 axolots into a boat, the axolotl model is off compared to the boat

To  reproduce this do:

1. place a boat down 
2.  summon 2 axolots and push them into a boat. if you do this a few times, one will have a "funny " model like so

I have done some playing around and it mostly works when the boat faces the -x axis
