The programers seemed to have left half of a landing/hanging animation in the game for them. If you whistle for them to land, they do a little back flip like they're going to hang upside down on their feet. They can't land or hang though sadly and most likely will never get an update considering how old the tame is and with the addition of the Des. Pour one out to pay resects to all those onycs who will never get TLC from the devs.
One time long ago I was following my friend into a cave to get the artifact of the skylord and lo and behold a lvl 480 bat appears me thinking with 250 melee damage with an ascendent sword I went after it and got one tapped keep in mind I was in full ascendent chiten armor later we went into the dungeon and first room I met lvl 550 bats in there it was a war zone I got killed real quick the sad thing is my friend barely lost any health and to this day I am not going anywhere with my friend.
Once my friend and I spawned one in to force tame so I could ride it. Let’s say it looked a little strange since you start bouncing when you click a button or something. Also the size difference is amazing. Recommend.
