Heya! I've got a question here from Nick:
"I've been farming a boss for 2 days now for a pet called Zombie it looks like Grubb but umm
Is it confirmed to be dropped?
Thanks for sending a message, Nick. Yes, the zombie pet is confirmed to be dropped by a boss named Grendel Madlings.
A good way to know something is verified as dropped is by checking out the player-made wiki for the item: Zombie Pet. Knowing KingsIsle as I do, there really would be no reason we'd ever remove this pet from a loot table . . . on purpose. And to be honest, I highly doubt anyone has modified or even thought about the Grendel Madlings boss in years, so I'd give it a 99% assurance that it still drops. Also, taking a look at that player-made wiki page, it also looks like it drops from the Purreau's Plentiful Pet Provisions Pack. That should make it quite a bit more available out in the wild.
To be honest, your best bet is probably signing up to a site like Wizard101 Central and asking if someone has one to hatch with you, like this person did back in 2014. Wizard101 Central has a super active pet hatching group and I'm also about 99% sure someone there would hatch with you if you post in the Pet Mixing Meetups forum. Or alternatively try using the #W101 hashtag on Twitter to see if anyone could help.
Hope that helps and best of luck with your pet hunt!
