Jay knows that Kai's up to something.  He surreptitiously watches Kai place something into a small duffel bag and zip it up, muttering to it.  "It won't be long now."  When Kai walks down the hallway, Jay addresses him.

"Hey Kai, what's in the bag?"

"Uh, n-nothing."

"I'm not buying that, Kai..."

"I've got to go, Jay!"  Kai interrupts, running past him.  Well, now I've got to know.  Jay thinks.

He follows Kai from a safe distance into New Ninjago City.  Kai ducks into a shop and reaches into his duffle bag to pull out.. the chicken.

Jay looks up at the shops' sign and grins.  He steps into the shop a few minutes later and snaps a picture with his phone.  "Wait'll Skylor sees this!"  He crows.

Kai has his head leaned back on the headrest of a spa chair, the chicken in a tiny chair beside him, both of them are getting a massage.  

The chicken clucks contentedly.  "Cluck."  (Join us, brother.)

Jay hesitates, then shrugs and settles down beside them.

Kai sighs.  "This is the life."

"Cluck."  (Mm-hm.)
