Always Identical Twins: Little Miss Twins are a pair of identical twins; they are based on Roger Hargreaves' twin daughters, Sophie and Amanda. Mr. Clever and Little Miss Star host a show called The Misterland Breakfast Chat. It's a news show where they tell about what's happening in Misterland. They start talking about how exciting Christmas is. But then there was an emergency broadcast from Mr. Nosey. He said that Miseryland was not excited about Christmas. Even worse was that the queen had a horrible plan to ruin Christmas. She told her knights that they had to go to The North Pole and steal presents at Father Christmas's workshop and tied up him, Mr. Snow, and the elves. So Mr. Impossible, Little Miss Magic, Mr. Rush, Mr. Strong and Mr. Busy had to go and save Christmas. Soon Miss Magic started to wave her wand and made everything run at double speed. Then the new batch of toys was finished. Just as they finished, the Miseryland knights (who got lost in a snowstorm) returned with the original batch of toys.

The Ditz: Mr. Dizzy starts out living up to his name, coming up with bizarre answers to simple questions asked by a pig and an elephant purely to rub in how clueless he is (such as naming a mouse as a big animal with big ears).

Oh, My!: The characters who appear to be simple shapes with human figures regularly interact with regular-looking humans.

Mr. Dizzy lives in Cleverland, where everyone makes fun of him. He drinks some magical water and becomes the smartest man of all.

Mr. Walk is the face character of the Fashion Walk campaign alongside Little Miss Fashion, forming "Fashion Walk" together.

Mr. Quiet is the 29th book in the Mr. Men series by Roger Hargreaves. Mr. Quiet lives in Loudland, where everybody and everything is too loud for him. Loudland would be suitable for Mr. Noisy, but not for Mr. Quiet. Mr. Quiet is scared. Whenever he tries to go shopping, he can only whisper what he wants, which results in the grocer, the milkman, the baker, and the butcher shouting "CAN'T HEAR YOU! NEXT PLEASE!" One day, Mr. Quiet gets a letter from Mr. Happy to stay in Happyland, where Mr. Quiet gets a job in a library, where the rule is to always be quiet. Mr. Quiet is so happy he laughs out loud.Mr. Messy is the 8th book in the Mr. Men series by Roger Hargreaves. Mr. Messy is pink and really messy but has a really nice smile. Mr. Messy lives in a messy house until Mr. Neat and Mr. Tidy come to clean his house and give him a bath (his first ever, as the bathroom had previously been the messiest of the house). He becomes neat and thinks he has to change his name. Mr. Messy then becomes clean. Forgetful Jones: Mr. Forgetful has an absolutely terrible memory. When asked to tell Farmer Fields that one of his sheep is loose in the lane, he draws a blank when he actually encounters the farmer and instead tells him that a goose is asleep in the rain - which means nothing to Farmer Fields, as he doesn't keep geese and it isn't raining. In "Mr. Dizzy", this trope is discussed when Mr. Dizzy ( who has become smarter) asks an elephant what's large and gray and says, "Dopit! Dopit!" When the elephant claims that no animal says that, Mr. Dizzy ties his trunk in a knot. The elephant then tries to yell, "Stop it!", only to say, "Dop it! Dop it!". The Un-Reveal: In "Dr. Twelfth", Missy was causing trouble Twelve by stealing artifacts across time and space. At the end after being caught, Missy wants to tell Twelve on why she was doing this. But Twelve doesn't want to bother and leaves for lunch, so we don't get any reveal on what Missy was planning.
