Cricket and Tilly Green have a very good relationship. Both of them are the main characters of the show and are the characters who have appeared in the most episodes (Tilly was absent only in the episodes "Date Night", "Starter Pack" and "Hands-On History", while Cricket has no absences outside the shorts).
While Tilly is the older sibling and Cricket is the younger sibling, Cricket usually acts as the straight man, as opposed to Tilly's odd and silly tendencies. However, Tilly occasionally does act like the big sister, such as in "Cricketsitter", when their dad left her in charge of Cricket. Cricket and Tilly deeply care about one another and are very close friends as well as siblings, despite occasionally getting into big conflicts, and being at odds with each other at times.
