Okay this one will be a little different from the others as it will be divided between the lore of the mascot and the monster So let's eat with the lore of the mascot

ZardyDav (it had to be Zardy XD) went to the poppy playtime universe and went to playtime co. And he paid them $696,969 to make some mascots:

High five a more relaxed and RADICAL version of huggy Wuggy who likes to give high fives

Bunny long legs the pet rabbit from the long legs family

And singing fox who is the singing member of smiling creatures

And now let's get to the monster lore:

The high five is one of the daycare mascots where he would teach in a RADICAL way the correct lengths and not things like the middle finger.

The bunny long legs would be a daycare mascot in one part but teaching children how to care for animals

As for the singing fox, she would be the smiling creature that would help children learn to sing with her gas (which is from a fictional plant) to make children sing better

At the time of joy, they were the bigger bodies who barely participated in this, they were more involved in picking up the corpses and leaving them in a hole.

When the corpses were finished, they decided to leave the singing fox without eating to starve her (that's why she's so thin)

High Five was one of the first bigger bodies to be cannabalized after human corpses were eaten and he died, but Bunny Long Legs rescued his corpse to try to revive it later.

The bunny long legs stayed hidden and that's why he wasn't killed by anyone and managed to rescue the singing fox from being almost starved to death.

But then one day Zardy decided to visit Playtime Co. And so he saw the state of the place and took the animals he created, placed them in the Void (zardy's house) and created a warehouse in a clap of his hands.

Then he revived Highy Fivy with a somewhat zombified appearance and added Felix Tiger and Rock Crow from the previous draw

But then comes the question: okay, but what about the demon bull, the angel sheep, the angel demon amalgamation, where are they?

Well they are at Afton Robotics rotting to this day :D
