Measurement: using standard measurements to compare capacity.


Olive and Otto are on a case where a woman has two left feet. Olive zaps her right shoe and turns it into a left shoe so it fits. Back at headquarters, Ms. O shows them her new plant, with immediately sprays her with pink dust. Dr. O says it’s safe, but just in case, she’ll take the plant to the medical bay. When they get there, Dr. O says it’s actually incredibly dangerous, but if you know it’s infected you, it turns you odd even faster. She also informs them that they have one hour to cure Ms. O or Ms. O will stay weird forever.

Ms. O already has an enormous ear. Dr. O explains that the antidote requires four ingredients, starting with a quart of unicorn tears, which she has with her. Next, she needs a quart of Loganberry juice. As the agents go to leave, they see that Ms. O has a red unibrow.

They arrive at the tree and see Logan the Ogre. He starts to attack them, but stops and lets them collect it. Otto mashes the Loganberries into juice with his feet, and they return to headquarters. Ms. O now has a tail. Dr. O tells them they need a quart of Baby Genius’s giraffe milk.

They entertain Baby Genius in exchange for 4 cups of giraffe’s milk. They come back to headquarters, where Dr. O has hidden all the mirrors so Ms. O can’t see herself. Then Dr. O adds a quart of water. Ms. O arrives with wings, but Dr. O pours the antidote on her head and cures her. And that’s when the plant sprays Otto. He asks whether they should go back to the ogre.


  • The puffer plant in the video is similar to the one in the training video. However, in the training video, after 60 seconds, a person goes back to normal, but permanently turns into a chicken.
