When looking for a lizard nanny, do these steps:

Step 1: get on your argy

Step 2: locate the area where they spawn

Step 3: find one, trap it

Step 4: start knocking it out

Step 5: try to put food in inventory to tame only to realize another tribe got the last shot even tho you trapped it in your trap.

Step 6: get on your argy

Step 7: go home, cry, and pike a dodo

There is a mod called maeguana spawns and it adds maeguana to all of your maps. Very good mod.
