The Phantom Forest - S1.E4

The girls decide to help Louie, who immediately causes trouble with a magic demon-summoning whistle. While the girls are busy handling demons, Louie goes toe to hoof against a wild boar.

The group finds a suitable trree, but a beautiful elf named Celecia interrupts them. She promises she can find them a better branch in the elves' village. The girls are skeptical, but Louie overrides them and inadvertently leads the group into a trap.

Locked up and facing certain death, Louie proposes a means of escape so stupid, it just might work...
