Water leaper

A frog-like flying creature that appears in swamps and is a hostile mob.
I usually spend time in the water.
Therefore, you can swim.
However, if you detect that there are players, chickens, cows, sheep, pigs, or spiders nearby, they will attack you immediately.
Furthermore, even in the water, it may attack fish other than blowfish, axolotl, squid, and glow squid.
In addition, the frog transforms into this mob when hit by lightning.
However, you cannot land because you are always flying.
Instead, you can swim by jumping into the water.
If you have any other good ideas, please let us know in the comments.
Thank you for taking a look at my idea.
