Wouldn't surprise me, and that just makes it even worse. I thought the animator who does these made them from scratch, and I thought they said that, but him ripping them from a game makes this even lazier. And the fact it takes several months to put out between episodes is bad considering they're telling a serialized story dependent on previous episodes for HFIL.
12 episodes, including the Christmas special, in almost four years... Even at his slowest, Kaiser wasn't that bad, which is saying something.
