You will most likely receive a leprechaun or a jade oni! That's it! You can check on the Wizard101 Wiki Pets website to see ALL the possible mixes you can create! Good luck and have fun!
Sorry, but there is no hybrid between Jade oni or leprechaun. that only gets you either one of the pets with a different pedigree. the only legit hybrids come from 48 pets, promo pets, and unicorn (yes they can make a hybrid). Enough said.
