It was another day at Acme Looniversity, and the students are getting ready for class with Daffy Duck. Plus, today is Valentine's Day, and a few of the students were already spending the day with a special someone.
Fowlmouth wants to spend the day with Shirley, since he has a mad crush on her. He only hopes that she won't spend the day with Plucky.
"Hello, Shirley", Fowlmouth said as he approached his dream girl.
"Oh, hello", Shirley replied.
"Hey, uh, I was wondering if you would like to be my lovebird for today, I hope I hope I hope."
Shirley placed her hands on her hips & stared at Fowlmouth with suspicious eyes.
"Like, only if you promise to go the whole day without swearing."
"I promise, I'll try my best."
At that moment, Daffy Duck entered the room.
"Good morning, class", he said as everyone scrambled to their seats.
Daffy Duck teaches a few different subjects at Acme Loo, but his main, and favorite, subject is how to steal the spotlight. He is, without a doubt, Plucky's favorite teacher.
Once everyone got to their seats, the black duck continued.
"Before we begin, I'd like to wish you all a Happy Valentine's Day. I hope you all have someone special to spend the day with."
As Daffy continued speaking, a paper airplane flew around Fifi's head & landed on her desk. She opened it & read it.
"Aw, Furrball", she said.
"What?", the blue cat replied.
"Zhis letter eez tres sweet."
"What letter?"
"Zhis one."
"I didn't give you that letter."
"Huh?"
"Lemme see it."
Fifi handed the letter to her boyfriend, who immediately read it. Almost right away, he recognized the handwriting.
"Wait a second...", Furrball said before he & Fifi turned around to see Elmyra waving at them.
"Sacre bleu", Fifi said.
"Just ignore her", Furrball replied.
"Anyways", Daffy continued, "today we are going to learn about painted tunnels. Now, the idea here is to fool someone into going into this fake tunnel & ram right into it instead. One way of doing this is by..."
As Daffy continued with his lesson, Furrball turned to Monty & whispered, "Hey, Monty."
"What do you want?", Monty whispered back.
"Listen, you like Elmyra, right?"
"One way or another. Why, is she being a pain again?"
"Don't you know it."
"What do you want me to do about it?"
"Just try to keep her away from me & Fifi. The last thing we want is to spend Valentine's Day in cages."
"Alright, I'll do my best."
"Excuse me", Daffy said, "I don't appreciate it when other people are talking while I'm talking."
"Sorry, Professor Duck", Furrball said.
"Thank you. Now, I will need a volunteer for a little demonstration. Plucky?"
"Yes sir?"
"Come on up here."
As the green duck joined Daffy, he was given a paint can with a brush.
"Paint a tunnel on that wall."
Plucky took the brush & painted a perfect two-laned tunnel leading to a forest environment.
"Now I want you to call on someone to test your tunnel."
"Okay, I choose Buster."
There was a bit of murmuring going on as Daffy said, "Buster, come on up here."
"Don't mind if I do", the blue bunny replied. Buster & Plucky both have a similar rivalry like Bugs Bunny & Daffy Duck, even showing their support, with Buster saying that Bugs is the greatest cartoon legend ever, while Plucky would disagree & say that it's Daffy.
As Buster joined the two mallards in front of the class, Plucky spoke up.
"Hello, Buster, old friend."
"Hello, Plucky."
"What do you think of my little tunnel right here?"
"I think it looks nice."
"Would you mind trying to go down this tunnel & see what's on the other side?"
"I suppose I could."
At that moment, Buster revved up his legs & zoomed off into the tunnel, but instead of crashing into the wall like everyone thought would happen, he continued on down the tunnel, as if it was real, and stopped at the other side.
"What?!", Plucky exclaimed. "Impossible!"
"Everything looks fine over here", Buster said.
"I'll show YOU what looks fine."
At that moment, Plucky ran toward the tunnel, attempting to follow Buster, but instead he crashed right into the wall. The class responded with roaring laughter, as Plucky slowly fell off the wall & into the floor. Daffy spoke up.
"Okay, yes, ha ha, very funny. Now Buster, come on out of the tunnel."
"Come & get me", Buster said as he ran off & disappeared.
"Oh-ho, you're in for a lot of trouble, Buster."
Daffy backed away from the wall & did a running start toward the tunnel, but just like Plucky, instead of going down the tunnel, he crashed into the wall, causing everyone to burst into laughter once again.
After Daffy fell to the floor, Babs asked, "Where did Buster go?"
And soon enough, the classroom door opened & there stood Buster.
"Here I am", he said.
Plucky looked back at Buster in anger & disbelief as he said, "How did you do that?"
"I can sum it up in a word: magic."
"Magic?!"
At that moment, Gogo Dodo, whose on his 'school bell' duty, popped out of the clock above the chalkboard.
"CUCKOO-CUCKOO-CUCKOO! If you don't believe in magic, then you are CUCKOO-CUCKOO!"
As the green bird slipped back into the clock, all the students grabbed their stuff & left the room.

Later on in the library, while Fifi was looking for a book to read, she spotted Furrball sitting at a table, reading "Call Of The Wild" by Jack London. Slowly & silently, she snuck up behind her boyfriend & covered his eyes with her tail.
"Guess who", she said.
"Hmmm", Furrball said as he put his book down, "I recognize the tail, and that voice, and the smell. Could it be my sweetheart, Fifi La Fume?"
"Zhe one & only", Fifi replied as she spun the chair around & jumped into Furrball's lap. The cat & skunk held each other, happy to spend Valentine's Day together.
"Happy Valentine's Day, Fifi."
"Happy Valentine's Day, Furrball."
After romantically staring at each other for a moment, they moved in for a kiss, but Monty spoke up as he walked by.
"Get a room, you two."
"Shut up", Furrball quickly said. After the human toon walked away, the cat & skunk attempted to kiss again, but Sweetie Bird flew in & started taunting them.
"Furrball & Fifi sitting in a tree, K-I-S-S-I-N-G!"
At this moment, Furrball was starting to get annoyed.
"Don't make me come after you, Sweetie!"
"Ha! I'd like to see you try."
"Alright, that does it!"
Immediately, Furrball jumped out of his chair & started chasing the pink bird all around the library as Fifi looked on.
During the chase, Furrball bumped into a few people who were carrying books, knocking them out of their arms.
"Hey!", shouted Dizzy Devil.
"Watch it!", exclaimed Mary Melody.
Furrball then bumped into Shirley & Fowlmouth, knocking their books out of their hands.
"You dad-gum pussycat!", Fowlmouth yelled out.
After about a moment of chasing Sweetie around, the pink bird stopped at a bookshelf. She turned to Furrball, who had a predatory look on his face.
"I got you now", he said. The blue cat jumped to the pink bird, but Sweetie immediately flew upward, causing Furrball to crash into the bookshelf.
"OOF!", he said. At that moment, the bookshelf he crashed into fell backward, and all of the shelves started tumbling like dominos as the students quickly moved out of the way.
After a moment, every single bookshelf in the library was knocked over, books scattered everywhere. Bookworm entered the library after taking his break, and made a face of genuine shock after seeing the mess of tumbled bookshelves & books in front of him.
Just then, Furrball popped his head out from a pile of books & turned to Bookworm, who looked at him furiously.
The blue cat smiled nervously as he started sweating.
"Heh heh heh. Whoops."
