Two apes only?[]
I'm not sure if this is still the case, but at least at one point, there were only two apes in GF. It was very easy to think that there were three but in fact there were only two. One in front of the Pirate Camp, the other one spawned at the remaining two places. I used to farm these as a Daredevil and I could see on my map when minibosses were spawned, there were never apes at both spots (which is why you could wait forever at one place and not see an ape, if no one smashed him while he was at the other spot he would just stay there). The ape did not automatically alternate, so even if he was smashed he may just appear at the same spot the next time.
