And again, apply to what I just said to the observations.

Also, arbitrarily? No, it'd be completely beneficial if it had durable skin as that would be the first line of defense if it had a hydrostatic skeleton considering it isn't under water.

Also also, the "musculature" of the Lion's Mane Jellies also extend to the oral arms and not just the bell (though not large enough to compare to the bird blob)

This is the central crux of finding logic in alien fauna. Most people only apply concepts we know from our own planet. When the glaring possibility of it being a concept we currently have no idea about.

And, just to entertain, let's say we apply concepts we know. A large blob-like bird creature has an extremely durable skin to prevent itself from bursting from maintaining its shape via a hydrostatic skeleton. It's skin, and the layers (presumably muscle and mesoglea, for the lack of a better term) beneath it are elastic enough to allow the creature to either distend or contract it's body at will into various shapes. When on the ground, it can take in air to maintain a more rotund form, it can also release the air to flatten itself into a disc and propel itself in the air not unlike the bell of a sea jelly.
