Little Miss Naughty Goes for a Swim is a story from the 2000 Annual.
Plot[]
It was the hottest day of the year in Misterland. A day so hot, nothing could stay cool and Little Miss Naughty was at her naughtiest. There was only one place the Mr. Men and Little Misses were at on a day like this: the local swimming pool. And that's where Little Miss Naughty stealthfully snuck into. She began to unleash several naughty tricks from underwater.
The first thing she did was swim to the deep end and tickle between Mr. Tall's legs. Next, she found Mr. Lazy sleeping on top of an airbed; the naughty deed she did to Mr. Lazy was tipping the airbed up, leading to Mr. Lazy falling into the water and waking up! After that, she saw Little Miss Greedy sliding down the water shoot. Just as Little Miss Greedy splashed into the pool, Little Miss Naughty gave her a nasty fright that caused her to retreat backwards up the chute!
Finally, Little Miss Naughty saw a plug at the bottom of the pool. With a cheeky grin on her face, she did the naughtiest thing she could think of. She pulled the plug from the plug hole and all the water drained from the pool. Little Miss Naughty fled before she could be caught; but Little Miss Tiny saw the plughole without the plug and Little Miss Greedy remembered seeing Little Miss Naughty when she went down the water chute. Mr. Tall began to refill the pool with a nearby hosepipe while everyone else was searching for Little Miss Naughty. Still feeling naughty, Little Miss Naughty crept out of her hiding place and played with the hose tap. This led to the hosepipe squirting water in his face.
This proved to be Little Miss Naughty's undoing. Because Mr. Tall was tall enough to see over the tap, he spotted Little Miss Naughty and got his revenge on Little Miss Naughty by spraying her with the hosepipe. Little Miss Naughty tried hiding in the water chute, but Little Miss Greedy got back at her by sliding down and pushing Little Miss Naughty into the half-empty pool. Little Miss Naughty tried to climb onto Mr. Lazy's airbed only to accidentally pull the air stopper and whiz all around the pool until all the air was out.
By the end of the chase, everyone was hotter than before. With the pool refilled, everyone splashed back into the pool and resumed their swim. But not before warning Little Miss Naughty to stay away from the plug.
