Chronic Hero Syndrome: While worried about being late for tea at Little Miss Bossy's, he did delay himself so he could help Mr. Messy and Little Miss Somersault.

In promotional artwork and a brief scene from " Physical", Little Miss Whoops has an X-shaped plaster on her left arm, which does not appear in the rest of the series. He's named after what he's made of instead of a personality trait, and thus isn't defined by any kind of personality trait. His favourite food is liverwurst (liver sausage), as mentioned in Beach, Construction, Picnics and Pests (US version). Rhymes on a Dime: When using her magic in both the 1995 TV series and 2008 Mr. Men Show, Little Miss Magic often uses long rhyming incantations as she does so.He displayed anger in " Boo Boos", " Hotel", and " Up and Down." His segment with Mr. Stubborn in "Boo-Boos" had more feelings of anger, but were cut as the directors said Mr. Happy wasn't allowed to be angry. Ironically, he is also one of the Angry Heads (sometimes). He seems to be prone to depression, as shown in books like "Mr. Nobody" and "Little Miss Magic" and in the episode of Mr. Men and Little Miss, " A Very Happy Day for Mr. Happy", where he was depressed for days, (though those reasons above were because other people were unhappy). With the book series’s success, the BBC released several animated shows and songs about Mr. Men and Little Miss. Hargreaves’s creations captured everyone’s hearts in the 80s, and they continue to do so today.

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. It then became a cause for concern as Father Christmas found there was too much snow to deliver the presents to the children. He had to find someone to help him. In Little Miss Dotty Goes To Home Farm, she gets thirsty enough to drink some fresh milk out of the barrel. Friends: Little Miss Sunshine, Little Miss Neat, Little Miss Tidy, Mr. Snooty, Little Miss Helpful, Mr. Happy, Mr. Messy (sometimes), Little Miss Trouble, Mr. Strong (sometimes)

Little Miss Magic

Although he wants other people to be happy, in the books, he was nearly always happy in the series. He tends to hide his other emotions (sadness, fear, anger, etc.) behind his grin. An example of this was in " Boats" was when Mr. Happy had a smile to remain positive when the S.S. Stubborn was sinking.
