I get 2 dilos, every level up I use on melee. My strongest male and female have about 400 on melee, 300 each on speed. I just mated them (their names are Dumb and Thumb), Im currently watching the offspring be incubated.
Update: IT HAD TWINS
Both girls with melee about 300, both level 37. Ive never seen twins, in ONE egg. And the mother is a vibrant red its a shame they both came out greyπ
