I have a few dream pets that are going to likely be hard for me to obtain because I suck at saving up NPs and I don't cheat because I'm chickenshit. The hardest one for me to get is probably going to be a specific pet of mine turned into a mutant Acara. I love them, dunno why.
i love the water wraith and maracite but i have a VWN/RW shoyru i want to paint and only can be wraith so i will have one extra i'm saving im going to do the wraith
If you want profits : sell the shell or make a mara/eventide/chocolate/water draik
If you want a nice pet : I really like maraquan shoyru. Or at least use the FFQ for an expensive colour or one that you can't have whitout zaping.
