Host drag weight over 900 = Bronto, Giga, Carcha, Megachelon.

BUT baby inherits Stat POINTS, not stats, so a mega mutated Giga with zero points in all but Melee is a bad plan as you will likely inherit a bunch of low stats.

If you’re looking to max out your Rhynio, try and find a host with a good spread in HP, Stamina, and Melee with a bit of weight for good measure as resin ammo is heavy. I reckon you’re more likely to find a decent spread in a bronto than a Giga. My best so far actually came from a bred Yuty. Even though I lost a percentage of stat carry over due to the lower drag weight, the stat spread was way better and made up with a better baby in the end. Oh and make sure you have all the cravings ready because it breaks your heart to grind for two days and then get a golden egg craving on the second one. Take your hesperonis fishing. Every five fish it eats you get an egg. Every four eggs or so you get a golden one. Be ready to run to a refrigerator because they spoil crazy fast.
