I think that in gardening there should be a sprinkler you can buy from the crown shop. It would be a housing item, but cost no energy, and waters your plants for you with a click on and a click off.
One thing I would love to have is a storm shark pet Just think about it for a second Another one is a scorpion pet I don't know it seems like a scorpion would be amazing And maybe a spell for every school tree like Niles summoning a giant sandstorm and maybe that would be a level 100 spell hmm seems nice
I do like the idea of having a Dr. Von Monster Pet. It can be another pet that has the "Dr. Von's Monster" Item card, but gets it at Ancient. It's dance can be the Thriller dance and would love to eat candy snacks.
Another neat pet idea would be called "Trick-or-Treater". It can be a Death Pet and look like the Elf but with a Death Leprechaun-style color scheme and can have either a "Poison" or "Death Elf" Item card (Death Elf can have 200 damage plus 700 DoT, being a rank 4-5 (Your choice)).
Another idea I had in mind was for Transformation elixirs. One can be a Ghoul Transformation (Because being a Ghoul would be awesome) and the other can be a Scarecrow Transformation.
