That's what I would have said too.

I'm not sure why but back in the days when those videos were released those things were always referred to as Meetles, but honestly I can't seem to see how they are the same as those:

Maybe special requirements are needed to make them like that, like when they eat meat or vegetables and change. I have no idea what those requirements could be though *shrug*

Yes,

It was never determined whether Meetles only ever had herbivorous and carnivorous outcomes, the first of which could become a balloon, or whether there were a number of different resulting forms a growing Meetle could develop into. One wonders what, precisely, the Meetle would have to eat to become a balloon or a boat.
