By breeding an Entbrat with any of the 3-element natural monsters on Plant Island. As far as we know, the chance of success is about 1% per try, regardless of monster level, monster happiness, or which 3-element monster you use. Using a T-Rox instead of one of the other monsters lets you try more often, because the failures will be T-Roxes, which have a shorter breeding and hatching time than the others.

Having Wishing Torches lit increases the chance of success, by about 1% per torch.

There aren't any especially easy ways to succeed in this. You just have to keep trying.
