Tetsukaburu's eyes are not large enough or in the right place to assist swallowing in any way. Out on the front of the head, deeply inset and small, they would not be able to force down on the animals throat.

Frogs do have teeth, although they are very small. Good for holding small things but not the great big flat molars we and other animals use for chewing. Tetsukaburu has big flat crushing teeth, which can be seen easily on the main photo for his page.

Attack anything that moves? Well, thats pretty much given in MH. Even the apparently timid gypceros will instantly launch a full out assault if it spots a human.

Purple and orange is really bad camoflage. Maybe a danger signal, like a ladybird or panda.

Also, this guy would need to have lungs. He is too large to breath through his skin. Not enough surface area compared with his volume.
