It was a quiet afternoon in the Central Park Zoo. Skipper, Private, and Rico were playing a slightly boring game of cards when they heard giggles coming from the lab.

"Kowalski? Are you okay?" Private asked through the closed door. "I think he's in trouble!" Rico waddled over and casually punched the door open. Kowalski was cowering in the corner, getting poked in the stomach by a strange looking robot thing.

"Hit the- haha -hit the switch!" Private rushed over to the machine and flipped a large switch on its back, causing it to whir and die.

"Phew, thanks Private," Kowalski said, catching his breath. "It was supposed to be an electric fish scaler, but I must've flipped the positive and negative wires-"

"I didn't know you were ticklish, Kowalski," Private said, a sly smile spreading across his beak.

"Uh, well... um... you see..." Kowalski stuttered, suddenly nervous. He couldn't deny it after what they had just seen. In a flash, Rico had him pinned to the floor. "AH! Rico, what in the world-" Rico began tickling his sides. "I'm-not-ticklish, Rico-it-was just-funny," Kowalski choked out, trying to keep back a serious case of the giggles as Rico's flippers treaded dangerously close to his stomach.

"Try his tummy," Private suggested, thinking this was way more fun than cards.

"No, wait, gah!" Kowalski yelped as Rico dug his flippers into his sensitive stomach. The scientist burst into laughter, squirming and struggling and feebly trying to escape as Rico tickled him half to death. Unfortunately for Kowalski, Rico was a bit stronger and a lot heavier. "Ricohoho! Stahahahap! You're kiheheh- You're killihing mehehehe!"

"Nope," Rico replied, grinning. The rest of the penguins were all chuckling themselves to see their brainiac friend laughing uncontrollably on the floor, utterly helpless. They knew that despite his pleas and protests, Kowalski was having fun.

"Getoffme, you big-" Rico jammed his flipper right into Kowalski's stomach, and the scientist was cut off by gasps of laughter.

"Do that again," Skipper said, standing in the doorway of the lab.

"I'm dying here, and you tell him to do it agAHA!" Rico took Skippers advice.

Finally Rico let up.

"I... am so... going... to get you... for this..." Kowalski panted, slowly getting to his feet. The rest of the penguins just laughed good-naturedly.
