It’s time to get psyched, K-Zoners, cos Nickelodeon’s mad music fest, SLIMEFEST, is set to rock the box in September. An intergalactic line-up of stars has just been announced! You’ll be singing along with Stan Walker, Justice Crew, Jessica Mauboy, Reece Mastin, Johnny Ruffo and more, not forgetting a special guest appearance from (yep) a tsunami of slime. Who’ll end up green and dripping? You’ll have to tune in to find out!

When: Saturday September 15 at 6pm (how many sleeps is that?)

Where: Nickelodeon

UPDATE: A second show has been announced! There will be a morning show on Saturday September 15, at 11:00am (the same day as the original show).
