Kuno was most probably imprisoned at or near the Elven Kingdom. If his guess was true, then he could travel back there, and encounter a Zerphy in its natural habitat!
He still had a problem of how to transfer and contain them to the rollercoaster, but he could solve that on another day. For now, he at least knew where to find them.
I could go there right now.
Of course, going into an unknown location could be very dangerous, especially if there were Zephyrs around. And since he'd be going to their home land, he could encounter tens or even hundreds of them at the same time. Combined, the explosion they created could level the entire continent off the face of the earth! Even he wouldn't survive from that.
If he did go there, then he had to be extremely prepared to fight them off, or be prepared for a stealthy entrance.
Thankfully though, he had a vehicle specifically upgraded for stealth.
