Belch-Champion Concept (NEEDS ART!)

So I was thinking about a new champion that spits out toxins and poison! Kinda like Toxicroak from pokemon xD. But with a long prehensile club tail. I do not plan to completely copy Toxicroak. Belch will have dark blue bumpy skin. He will also have a hairy dark bluish purple vocal sac.On his back he has a thick heavily spiked shell. His

Lore ideas so far: An incredibly prehistoric creature that has been frozen in ancient Freljord for centuries. No one knows how this beast showed up again. Rumors say that the creature was frozen inside a cave deep inside a mountain. No one knows how he got there. Once he had found the strength, it was like a sonic boom had hit the mountains. It had made an avalanche so big and so massive it had buried an entire village. Belch suddenly disappeared and never to be heard from again until now. (Based off Gnar's Story) Heimerdinger predicts that this avalanche was the reason Gnar was frozen in true ice for 40 centuries. Belch knows very little of 's tribal language. This is because Belch found Gnar's siblings and took care of them for a while since he felt sorry for what he had done. Fun fact- Belch eats rocks and dirt since Belch's digestive system is so strong, it melts the rocks and dirt into a sweet honey flavor.

That's all i got so far :c
