Yes. Though as far as experiments go, they're rather unorthodox. To be honest, I'm not sure I even fully understand how it is they're able to do some of the things they do.

[He's not even sure the malnosso fully understand how it is they're able to do what they do. If they did, there wouldn't be as much need to experiment, right?]

In the past, they've been able to do things like temporarily changing a person's age or gender, turn people into animals, or cause them to suddenly appear and disappear in various locations throughout the village. At the very least, they never last more than a week, and are usually more embarrassing than dangerous.

[Like that time Ion turned into a girl for a week and no one noticed. That was fun.]
