Does Pyukumuku also evolve? I find it hard to believe that it just... remains like that, although that's probably its purpose. What about Crabrawler? Does it evovle into a bigger boxing-esque crab of some sort? If these Pokemon do have evolutions, is TPC going to show them or are they going to leave them out? If this is going to be the case, then it's likely we're going to know anyway by the time the demo gets datamined, assuming it gets datamined extensively to the degree where we'll get tons and tons of leaks.
Pyukumuku I could see evolving at least once, while Crabrawler is what I predict being a standalone.
