The Tough Customers --- most of the kids in Arthur's class fear them, even though they're definitely not the most fierce as far as bullies go. However, when Muffy tries using the jungle gym they use as their Tower of Pain for a photo shoot, she starts a feud that has everyone in Ratburn's class on her side. Muffy, however, doesn't care about freeing the jungle gym, she just wants a good space for her photo shooting. And Molly doesn't really want to terrorize Muffy, she just wants her old place to chill back. More Info --- ECDC (thetvdb.com)
