When our heroes are infected with a virus, Rad stubbornly refuses to back down. 
- An indictor of Rad taking long to recover than Enid and K.O. was the color differences on their faces when they coughed after inhaling the fumes. Rad's face was blue while Enid's and K.O.'s faces were purple.
- Enid points out that Ernesto usually comes once a season as he previously battled by himself from "OK Dendy! Let's Be K.O.!".
- K.O. claims that he and Enid never gets to see Ernesto fight despite the fact that Ernesto had come to plaza to fight in "Let's Watch the Boxmore Show" and "Sidekick Scouts". It may have been likely referred to him fighting by himself as Enid pointed out that he usually comes once a season since "OK Dendy! Let's Be K.O.!" was the only episode in Season 1 to have Ernesto battle by himself.
