Octopony (Poniworld Chronicles #7)
Mortimer is an octopony—half octopus, half pony—who laughs at all the wrong times. He’s a joker, not a fighter, but it turns out the Nazi ponies have discovered an alien spacecraft buried in ice. And so Morty ends up having to travel to the Arctic to foil a nefarious plot to unleash an alien supersoldier into Poniworld. It’s all very exciting and dangerous, and so he giggles nervously sometimes.
