Screwy was a troublemaker in earlier episodes (Mostly to Billy) and was mischief, crude and immature. But in later episodes he wasn't bullying as much. He also likes parties. In the great defender of fun movie, Olie, Zowie and Billy invited him to Zowie's 3rd birthday. Around in episodes from the seasons 5-6 Screwy personality changed to a more mature manner. When Olie punched him in one episode Olie apologies For pinching him and gave him a kiss on the cheeks. He also has a soft spot, especially for his teacher. Even though in beginning episodes he bullied Olie, Pollie and Billy he never bullies the younger kids so it seems like he has a soft spot for little children. Even though he doesn't hang out with the other kids as often, Olie, Pollie and Billy are his closest friends and in season 6 he got more confident and became one of the gang. But it is unknown for Zowie, Wheelie and Binky but he had hang out with Wheelie in a few episodes and they seem to be good friends. He tends to have good ideas like in 1 time, Olie, Billy and screwy where working on a science project and Screwy made the idea of making a whirly, twirly copter and there idea was a success. He tends to be stubborn like in on episode Polina. Polie warned Olie, Billy, Screwy and Zowie if they burp on purpose too much there head will pop out and Screwy wanted to try that and he ended up doing it. Then realized It wasn't a good idea after all. As they blasted off to outer space.
