Regnos Region: 76-80

The first line here is actually a parallel to the Satelcast line, and part of why I was resistant to making the Satelcast line part Steel. Obviously they're based on UFOs, and while originally I went for a feeling similar to the Ultra Beasts I settled on more cartoony designs. The second line is based on teacup pigs and potbelly hogs, as well as actual teacups, teapots, and potbelly stoves. They also introduce a new mechanic I'm introducing in the Regnos Region, which is similar to PokeBlocks or Poffin. You'll see soon enough what the specifics of that mechanic are.

Boiling water fills the bowl-like section of a Kettlet's plump body, circulating through its body in a sort of secondary set of veins. The pleasant warmth leaves them very calm and docile, lounging around and boiling berries in their back before eating them.

Stovetop Pokemon

While a Potboilly sleeps, it cloaks itself in steam, partly to soothe itself and partly to hide itself from predators. They are extremely slow to anger, and pay small frustrations no mind.
