Trivia

 * The silk web is very tough; even Inidra's fire power cannot burn it.
 * Transformers fans will hear Arachne who sounds like Black-Arachnia.
 * During the laundry scenes, Ella and the other girls are wearing their Star Teen face masks (but not in their Star Teen outfits) to avoid smelling dirty and stinky laundry. This is the fourth episode to do so, the other three being Masked in Seattle, Reeking Havoc, and Beware the Dragon!.
