Actually it is Gadget's Go-Coaster

"WHEW," said Tiny Duffy. "No zombies!"

"Actually, it is a tiny roller coaster," said Tiny Shellie May. "And we are tiny as well, so it is very convenient."

I used to ADORE Gadget from Rescue Rangers. I do still like her but I was a HUGE fan when the Go-Coaster came out. It still makes me smile. Even if the ride is very, very short.
