Gripplis are humanoids that are clearly related to frogs. While some might speak Common, among their own kind they speak their own language called Grippli.
Grippli are common in Garund, especially in the Mwangi Expanse and the Sodden Lands. Grippli can also be found in Tian Xia in the Valashmai Jungle. Grippli are not commonly found in Avistan.
An article about grippli appears on pages 8-11 of Blood of the Beast.
