"Ow!" Dory stared at the swaying fronds on the sea anemone. She tentatively stuck a fin out, touching another frond. "Ow! That hurts!"

"Dory, what's all the commotion?" Marlin swam through the swaying fronds, watching as Dory jumped back in surprise.

Dory turned around, looking at Marlin, pointing to the sea anemone. "It bit me!"

"It bit you? Here, let me see." Marlin swam over, gently taking Dory's fin in his. He frowned, noticing a slight burn mark on her fin. "Dory, have you been brushing?"

"Uh…let me think…oh! Yeah! Yeah, I've been brushing."

"When did you last brush?"

"Uh…" She scrunched her face up in concentration. "P. Sherman, 42 Wallaby Way, Sydney."

"Dory, when did you last brush?" Marlin stated the question slowly, allowing the blue tang's mind to process the complicated question.

"Um…last week?"

"Last week?! Dory, that's to long a time to go without brushing! If you go without brushing for a week, the sea anemone will sting you! Don't you know anything?!" Marlin panted, trying to calm down.

"I know P. Sherman, 42 Wallaby Way, Sydney."

Marlin pinched the bridge of his nose with his fin before speaking. He took a deep breath. "Okay. Dory, I have told you time and again to brush every single day. Now, we're going to have to train the anemone not to sting you. But, you have to do what I say."

"Oooo! Like my conscience?"

"Yes, like your conscience. Are you ready?"

"I'm ready!"

"Okay. Now, I want you to swim up to the anemone and gently touch it with the very tip of your fin." He watched as Dory tentatively swam up to the one of the fronds, gently touching the tip of her tail to it. "Good. Now, do you feel anything?"

"No."

"Good. The tail is the least sensitive part of the body. Still feel nothing?"

"Yep!"

"Okay, now…Dory, what are you doing?" The blue tang was swishing her tail from side to side, causing the anemone fronds to move.

"I'm brushing my tail! It's fun! Whack! Take that you…you…"

"Anemone."

"Anemone. What's next Martin?"

"Marlin."

"Marlin. Right. What's next?"

"Well, now you take your left fin and gently touch the tip of it to the anemone and—"

"Wheeee! Look at me!" Marlin watched in horror as Dory darted in and out of the anemone, racing through the fronds. "This is fun! I wish Fabio was here!"

"Ne—nevermind. Dory, what are you doing?! I thought you said it stung you?!"

"It stung me?" She came to stop in front of Marlin, grinning. "What do you mean? It didn't sting me; I brushed yesterday."

"What?! Dory, you—you—how…?"

"Short term memory loss. I must have forgotten."

Marlin slapped his fin to his forehead as Dory continued to race through the fronds.
