You can see that the arms didn’t melt at all, so it’s more likely that they just put too many toppings on without an exposed crust to keep them in, causing them to spread off of the crust as they melted. I’ve done the same when I get overzealous with the cheese on homemade pizza. The crust underneath probably still looks like a minion.
I’ve been doing a few Duolingo lessons a day in Japanese for a couple years now. At the rate I’m going it’ll be a decade before I’m even slightly able to understand the language, but I don’t mind - it’s already been well over a decade since I first tried to learn it, so as long as this pace is sustainable, I’ll still be a lot further along than if I’d tried too hard, gotten burned out, and quit for a decade again.
