Grom's continuous pursuit of magical power and knowledge has brought some good results! This is his new standard size when he's not bipedal.

Arcane toads like Grom are commonly very large. Most of them are not too active and considerably lazy which causes their magical energy to build up but not truly develop. They reach the massive but relatively normal size of their species. Others make use of their magical ability but for several other reasons other than self development, they are generally quite smaller than the others of their kind but tend to fit in with the standard folk more and are quite liked for their magical knowledge.

However there are extremely few that are active but dedicate a lot of their time into a bit more selfish pursuits. In Grom's case, he uses his vast magical prowess to gain even more magical power. While he is capable to alter his appearance to fit in better when walking amongst the common people, his efforts have caused him to naturally be enormous, even beyond what the standard of his kin is. He is quite possibly the largest of the arcane toads and, due to how their bodies work, the most powerful as well.
