While swimming in the form I noticed that the swimming animation looks a little off from an outside perspective. Unlike with the Regular Tiger Shark, or Other Sharks (I think Latex Eel too-) not the whole body waves, nor moves at the same pace as the head. With the Squid Tiger Shark, the head does the waving normally while the body only moves from side to side without waving, and also does so slower (or less), which makes it look like that the head is bobbing side to side. It looks a bit weird in my opinion.

With the tail, as the legs/rear paws are on the same level as it is, as well as trying to do the default leg swimming motion, it's clipping into them, which makes it look not as nice as it could be. I think lowering them and waving from side to side like with the regular Tiger Shark instead of the normal swimming leg motion would make it look a lot better and cleaner. Or just lifting/tilting up the tail a bit, to avoid it clipping into the paws could do the trick, I think.

Maybe it's currently trying to do both the Squid Dog and the Tiger Shark swimming animations, which results in this slightly off outcome. Changing the current slightly, like how I suggested, could make it look a lot better. Or sticking with either the Squid Dog or Tiger Shark animations could maybe be an easier fix, at the cost of a unique animation, but not my mod and I know it can be a bit difficult to do things like this.
