Trivia

 * Eleventh time the girls are wearing Star Teens masks not only as Star Teens. Plus, it is the third episode so far where the girls are masked entirely during this episode (the first three being Masked in Seattle and the second Terror of the Woods). Here, the girls are masked when they're helping Ella doing chores around the house.
 * Ella dusting her room
 * Inidra taking out garbage
 * Sandra cleaning every bathroom and kitchen
 * Felicia mowing the lawn, blowing cut grass and leaves off with a leaf blower, and killing the weeds at the same time
 * Lisa vacuuming every carpet and sweeping the patio
 * Tanya washing the clothes
 * Sheila spraying bug spray on cockroaches and ants around the kitchen
 * Very similar to the Totally Spies episode "First Brat".
