i would say he is still a bit small to get pinkies. but ofc it depends on the size of the pinkies to >.<
well, there is a way that almost always works, but its kind of brutal:
take a needle and puncture the pinkies head, im pretty sure your tokay will be more intrested then.
if not, well then your tokay really dont want pinkies. every animal is induvidual, and some oviously prefer good ole bugs^^
