These things are awesome when starting. Me and my brother managed to tame a 450 and 300! (It took a bit because of the high levels tho). They could kill pretty much anything! Not a giga tho lol. We would travel the map collecting notes and finishing pursuits. The iggys “Nugget and LemonDrop” could seed fruit when we started to grow crops. And since they have infinite stamina when running on all fours we could basically escape anything that was too strong to fight.
