This brand-new series adventure series filled with laughs, danger, and facing fears, follows Freddy von Frankenstein and his monster big brother, F.M., as well as and his adopted sister, a were-cat named Riya, as they explore the supernatural mountain they call home and discover all the fantastical creatures living there!

Freddy has started a Supernatural Action Search Squad with his brother, F.M., to track down the fantasticals that have started coming to their mountain. The S.A.S.S. is mostly an extra credit project to get him out of doing actual homework, but when he boots up his newly fashioned motion sensor, they immediately get a reading! They rush off to check it out, with Riya, their sister, following close behind to keep watch over them at their dad's request.

However, as Freddy and F.M. speed off down the mountain, Riya hears a different creature in distress. She goes off to help the fantastical since she can see Freddy's target is just a lost mountain climber-or is it?
