The ending has the two villains sent off burning alive. Only if you stay for the credits do you get to see that after they turn crispy, they are eaten alive. According to Netflix, the movie is for kids from ages 5 to 7.
Kudos, though, for coming up with a plot that makes it easy to quote Troll 2:
"They're eating her. And then they're gonna eat me. Oh, my god!!!!!"
