@John Yakuza, if it could fight - then it is summon, not just a pet.
You talked about Abigail's Flower as I could remember

[GorillaGuru64]

I remember a specific type of plant you could find in the forest or the jungle that would summon a tiny ghost that would fight monsters for you, I completely forgot the name for it and haven't found anything about it
