It is in fact a Calypso - named Firecracker. It's a nice, interesting addition that will hopefully restore/bring back crowds and life in the 4th of July section. I mean I'm still waiting for a Screamin' Swing or HUSS Firsbee but yanno it's whatever
PS - In case you couldn't tell, I'm 110% kidding. I love Holiday World, and the fact that a small park like this can add a first-of-its-kind B&M, then two more relatively large additions still amazes me.
