If you feed him with a 10k Element Ore, you become only 25- 35% Effectivity, with 25k Ore = 50-65% and the Best gives the 50k Element Ore with 100% Effectivity. You can pull him with Carnevore Rex or Charca to the Element, just watch He gives your PET no Damage. Only the last 20-50 Meters you can feed him on the last Slot Element. Enforcers are very good to pull him.

Don’t get close to one with something big because they are aggressive

The picture makes it look sooooo plushy!

Dreadnaughtus won't spawn on my singlplayer and their saddle engram isn't appearing in creative; I may have been on easy mode but if there is a solution or reason may you put a tip on this category so I can see it?
