I'm really surprised, even disappointed that right now, this seems to be getting the most support of all the "joke entries", including ones like Ireland, Estonia etc... Because to me this is the musically and conceptually weakest one. I just thought it was cringy and unlistenably messy from the first time i heard it.
I guess they think it's more conventional, straight-up jokey Eurodance like they recognize from their youth, and in a way it's "more musical" than Finland, the problem is to me it's just cheezy and silly, and tries to hard to be funny with no points to make. And some might fall for the "serious emotional bit" at the end, to me it's just out of place and doesn't change my perception of the rest of the song anyway.
I almost expected it not to qualify for a while, but now that it's so popular, that's almost impossible, but who knows, really popular novelty songs (Aina mun pitää!) have failed before. Maybe the humor and appeals just works on a few countries who were used to Eurodance in the original heydays, and the rest will ignore it, we'll see.
