Best long process but worth it way-

1: tame 2 low level allosaurus and make allosaurus kibble (skip if want to but recommended)

2: tame a PAIR (same surname/same last letters) very low level griffin (10-30) with allosaurus kibble and 10x soothing balm from cave or just soothing balm

3: breed the park and make a LOT of griffin kibble

4: easily tame a high level griffin with 10x balm

hope this helps!
