We've seen Knifey's feline friend Kutty Kat in a comic before, showcasing her curated collection!
IDK if we should be glad or disappointed that Quest Sprout didn't pick the Life Knife, because it turns into a monster if it gets planted on the ground:
Also, I just noticed that Pest Sprout is wielding the Strife Knife in this exclusive comic promoting the Kargob Plushie:
I'm guessing Quest Sprout bought it for him as a trade for the shield!
