Tahm Kench frog skin (river frog)

Well me and probably alot more people would love to see frog Tahm Kench. A frog would be so cool, maybe when he eats things he changes multiple colors like a rainbow surging through him when he has something eaten. A Pshycedelic frog it would make sense to he is the river king and frogs roam around in the river. Lore wise if you wanted to go this far, im not shure but maybe Tahm ate the frog and essential ( you are what you eat ) right? Anyway just a thought comments?...
