It backflips when you level him/her up

This is a passive tame. Like all passive tames, you must equip the item it requests in your hot bar and tap it to feed the item to the dinosaur. Once tamed, this dinosaur provides a 35% experience boost to your dinosaurs that are near it every 5 minutes when you use the social action to pet it. This is very beneficial and is suggested.
这是一个被动的驯服。 像所有被动驯服一样，您必须在热栏中装备它要求的物品，然后点击它以将物品喂入恐龙中。 一旦被驯服，当您使用社交动作抚摸它时，该恐龙每5分钟为附近的恐龙提供35％的经验提升。 这是非常有益的，建议使用。

Esta es una domesticación pasiva. Al igual que todos los domesticadores pasivos, debe equipar el elemento que solicita en su barra caliente y tocarlo para alimentar el dinosaurio. Una vez domesticado, este dinosaurio proporciona un aumento de la experiencia del 35% a los dinosaurios que están cerca de él cada 5 minutos cuando usas la acción social para acariciarlo. Esto es muy beneficioso y se sugiere.

In mobile when you pet it it will give itself and all of your tamed dinos/animals an XP buff

In mobile, if you feed your tamed lystro some narcotics (any), it will give itself and your dinos the xp buff. You can pet your lystro and when the buff expires, feed some narcotics, to extend its buff, so you don’t have to wait again to pet him. Up this to inform bobs

One of the funniest little dinos in the game.
Act like a dog
Walks and run like a dog
Gives XP boost

And he does a backflip! :D

Find a lot of rare flowers in beaver dams and use them to tame lystrosaurus, then use their eggs to get diplodocus. Use diplodocus eggs to get allosaurus. These dinos are a great way to move up fast on PvP servers by getting a lot of allosaurus

Taming one can be a good way to level up. Once tamed they can be pet to obtain a free buff to epericence for you and your dinos in range. Last about five minutes.

Amazing Creature, 10/10 beginner tame, it defended me from several packs of compys, love them all!

Tame a lot of these guys they would help with leveling up your creatures I would say like 10-15 or maybe less it's your option not mine.

These little friends can help your dinos level up. They are easy passive taming which is wonderful
