There's a god that can morph into any creature he wants. He wanted to sleep for a very long time (like centuries), and found a perfect place at the bottom of a lake that is connected to the open sea. Now, what kind of creature would be suitable for him to morph into?
- It has to be a big-sized creature (like a megalodon).
- It should be similar to an existent (or extinct) real creature, though it can be modified (e.g. he can be inmortal because he's a god).
- If possible, based on a creature that hibernates.
- I want it to lay at the bottom of the lake, but I didn't want it to have any kind of shell.
Bonus: When he wakes up, he's going to fight another kraken-like god. So I would prefer if he doesn't have to morph again just for the fight.
