What's a Fritz?

So yesterday I got an offer for a bunch of chests and 6x Fritz the chirpy penguin (pretty kewl design btw). But the hell does it actually do? I haven’t seen it before so I’d literally be spending blind (and the price for the whole package was ridiculously high - I could buy a thick pack of actual games for that kind of cash). Shouldn’t there be like an info button for the pals you get in offers? Right now it’s assumed the player knows all the pal’s specs, and that isn’t a good thing, I think.
