I pump pure speed on mine. Always. Nothing better than a Roo with 200+ speed.
These guys are great at gathering thatch. Maybe not as good as a Bronto or a deer, but they are so fun. I use any excuse to take one of mine out to get some thatch.
They make the same bite noise as a parasaur, which is disturbing, but hopping around from tree to tree is undeniably fun.
Had one of these in a multi server, named him Steve Irwin. One of the best transport tames ingame period, got around 30 levels because of him. I’ve killed rexes and broncos with this thing. Knockback is amazing, and can easily run away from a fight if things go wrong. Sadly, game crashed in a cave and he passed away. Rest In Peace, Steve Irwin.
