Why don't we have Mittens back?

The New bot sensei has voice lines that relate to mittens.

go play

The ducks took him (or her).

mayyybe...

Possibly

Here's your mittens.

Now shut up ! 

The bunny hears there's more than one way to skin a cat. So getting his back shouldn't be a major challenge.

Hey! Please be kind and relevant. The community wants cat skin and that's what they'll get.

Mittens playing bots fun. Also, Sensei isn't the same. I liked getting trash-talked while I was playing, and Sensei isn't as good.

I partly agree, but we haven't been able to play Mittens in over a year, and that takes the charm out of it too.

true but just wait until the next lore drop

Mittens has joined Elvis and the two of them are touring the galaxy.

You will see Mittens again when his wander-lust has been satisfied.

Or when Elvis gets tired of constantly being beaten at chess, and brings him back.

who is mittens

At some point they'd have merged into a single entity
