Continuing on from Episode 16, Ty makes a discovery that a mysterious new problem might cause some havoc on Max Avenue, and making a guest appearance from the Hit Netflix Original Show, STRANGER THINGS, is DUSTIN. Dustin appears through a portal that Ty suspects and later confirms is connected to the strange zombie outbreak that occurred not so long ago. Jack is woken up by this, and just to fall back to sleep again, Dustin, him and Ty chill out in the living room until the sun rises.
In another house/lair is Ten and Zero from the Ty and Friends movie, and they are waiting for someone. And finally, through a cross-dimensional portal walks a man in a suit with a purple tie. The man goes into his office to review the footage he recorded of the "VR" world (AKA a test portal for an alternative demension) and shuts it off. Due to Zero and Ten's defeat (which will appear in the Ty and Friends movie.) The man is very mad that they didn't destroy Ty and Friends. So he kicks them out of his lair so they can fend for themselves. (That man was Zero and Ten's creator. Zero and Ten are actually robots that are so well built that they'd fit in with a crowd of humans.)
Whilst walking away in the rain, Zero and Ten are spotted by Ty and Jack in the living room, and from there, we must wait for next episode.
