It isn't a guide yet so it's here atm!
Surely the undead creatures have already dominated PvP,
but since this Sunday they might invade whole Azeroth and more.
The Hallow's End shall begin causing spooky things to happen
and revealing ghastly beings, including our beloved companions!
[pet]Sinister Squashling[/pet] (Elemental, cageable) can come from the Headless Horseman,
both from the Loot-Filled Pumpkin at the Scarlet Monastery
and Crudely Wrapped Gift gotten after the village event.
Can also appear within Handful of Treats.
You can spend 150 Tricky Treats on it too but it seems to be redundant.
Over these years there are already quite a lot of them and you can buy one @ AH,
but keep in mind that you need to use an original item (not caged pet) during the event
to fulfill a criterium for Sinister Calling achievement.
[pet]Creepy Crate[/pet] (Undead, not cageable, uncommon) is needed to be found by you during the special quest chain.
When it hangs out with you, it devours critters using its mysterious powers.
Nobody knows what happens if an Unborn Val'kyr decides to save the victims…
[pet]Feline Familiar[/pet] (Beast, cageable) can be purchased from the event vendors for 150 treats.
It's probably the most iconic pet of this event because of its witch hat and floating broom.
It does account towards your Crazy for Cats achievement.
[pet]Cursed Birman[/pet] (Undead, cageable) can be purchased from the event vendors for 150 treats.
Looks like a Mr. Bigglesworth's relative – maybe it might take away his Naxxtraumas?
Otherwise, he can still bring quite a nice amount of gold as he's been on live (what?) for just one year.
Being an undead with beast attacks, he can take revenge on normally advantageous critters.
Sadly it doesn't account towards CfC.
[pet]Widget the Departed[/pet] (Undead, cageable) can be purchased from the event vendors for 150 treats.
Like the previous undead kitty, it's been brought here in 2014. It can surprise critters too.
In the German client it's called Schrödinger's Cat. If only it had 50% chance to start an encounter with dodge… Or like another poster pointed out, start either as a Beast or as an Undead.
Sadly it doesn't account towards CfC either. And does.
[pet]Ghastly Rat[/pet] (Undead, not cageable) came from the 6.2.2 patch notes without any complementary item.
A Warcraft Pets poster @Squeeky called some days ago that they are battled at the garrison when the Creepy Crawlers are used.
Has some advantages of Blighted Squirrels with both Crouch and Rabid Strike.
"By far the best way to spread the plague of undeath."
[pet]Ghost Maggot[/pet] (Undead, not cageable) is from that 6.2.2 patch note too.
An undead with Survival can have 3 rounds of ease regardless on its speed!
"If a live maggot eats the dead, what does an undead maggot eat?"
[pet]Spectral Spinner[/pet] (Undead, not cageable) is also from that patch note.
He can get 325 speed so he might become a new PotQ. I'm not even going to post why for the security reasons.
"As if a mine full of non-ghost spiders wasn't scary enough."
To get all purchasable pets without a squashling you need 450 treats – it's a rounded amount of them to get on one character.
If you're looking for toys you can need another 300 Treats. Additional 600 for villain costumes with 50 charges, 160 for consumable (no pun intended) Perky clothes and 5 for an Ominous Pet Treat.
Good luck!
Hehehe…
