Glog is Icklewoo’s cousin from Upside Down Underland. He can be a bit shy and, when he visits her at the School of Roars, he causes lots of confusion when he shakes his tentacles to say ‘sorry’ and the other monsters don’t know what it means. Glog’s favourite things are riding his scooter and eating cabbage mush.

His school in Upside Down Underland often teams up the School of Roars at special events like ‘School Roarovision’, where he has a ‘Roar-Off!’ with the class. He also takes part in the ‘Smelling Bee’ where he competes head-to-head with Wufflebump.
