Power Rangers : Season 1

When Billy receives his very first B, Rita who obviously can't tell the difference between the letter grade B and an actual bee, mistakenly thinks it would be clever to send down the Grumble Bee monster. Trini and Billy are forced to battle it on their own, as Zack, Kimberly and Jason are a little 'tied up' elsewhere.

Tommy and Jason are teaching a self-defense course for the mothers of Angel Grove, and when Rita hears Tommy utter the phrase "Two Heads are Better than One", she decides to take his advice for herself and sends down the two-headed Parrot monster to attack the Rangers.

Rita interrupts Zack's magic show at Ernie's Juice Bar, when she sends down the Peckster monster to battle the Rangers.

Kimberly is a contestant on a Halloween-themed game show by the name of Trick or Treat. She ends up having to forfeit when Rita sends the Pumpkin Rapper down to Earth and she and her fellow Rangers have to go stop him.

When Jason and Zack try and help a young boy, Roger, make the soccer team, Rita sends down her Socadillo Monster who plays soccer by his own rules.

When Tommy and Jason try to instill some good values into Angel Grove's youth, Rita, with her Slippery Shark monster, casts a spell on the two, making them hate one another

Kimberly's younger cousin Kelly is having difficulties obtaining a spot on the Angel Grove Cheerleading squad. When Rita sends down the Lizzinator and has Kelly kidnapped, she must escape by putting to use everything she's learned- and with a little help from the Rangers of course.

When Tommy is having trouble making the Angel Grove High Football team, Rita sends down the Rhino Blaster and a few putties to challenge the Rangers in a good old fashioned game of football.

Goldar and Rita select putties worthy enough to become evil Power Rangers. They are given the badges of darkness, allowing them to turn into the evil counterparts of the Rangers. They, along with Rita's latest creation, Commander Crayfish, are sent down to Earth to destroy the Rangers.

Zack wanting to impress Angela, buys her a pair of pearl earrings for her Birthday. The earrings, which have been cursed by Rita cause everyone in the room to freeze once Angela puts them on. This includes Kimberly, as well as Trini, Billy and Jason who were there to stop this very thing from happening. Now it's up to Zack and Tommy to stop the Oysterizer alone and undo the earring's effects.
