Man... gotta say. Gripplis and Minotaur (fortunately Southland Heroes by Kobold Press has got my Minotuar fix).

Actually, Southland Heroes I think could solve any Frog-man/Grippli issues you might have. They have a 'Saurian' entry, which on the surface is dealing with Lizardfolk. However! One of the alternative racial traits is called a 'Pygmy' which on one hand could be a 'small Lizardfolk' or you could describe/view them as Lizardfolk's fellow amphibians, the Grippli.

What kind of frog-men are you looking for?

The MM has bullywug & the slaadi, VGtM has Grung, but I can't find any Grippli. Aside from any "Frog Men" race for players, I can't think of any other frog 'men'.

Yes, whoever it was called it. It was just the same trick they pulled with the Tortles. Lets trash talk them on twitter and say we hate this race and then release it anyway once the buzz has been created.

At least it is for charity.
