It (Stephen King)

It, also known as Pennywise The Dancing Clown, is one of the main antagonists of the original Littlest Pet Shop Fan-Fiction series. He is Black Soldier's tertiary sidekick and one of Blythe's arch-enemies.

Stephen King's It (1960 - 1990)
In the original movie of the same name, he wanted to kill The Losers Club, but as he tried, he failed when he was the clown he was before. And by the time he saw some of the kids (now adults) from the Losers Club 30 years later, he was totally dead.

Littlest Pet Shop: The Fan-Fiction Series
He first appeared in episodes 5 and 6 of the Fan-Fiction series also of the same name, right after Blythe and her pet friends, along with Young Mi, Jasper, and Sue to Derry (the town where the clown monster lives - inside the sewers.) Blythe's dad bought a vacation house to stay in for 5 staightt months. Blthee and her friends were very surprised. Then, the first 10 days later, Blythe and Young Mi, made a paper boat together (like best friends do) and they ask roger if they can to sail it, Roger says to be careful (that's a yes) and he also says that if any monster grabs them, he'll beat them up. Later, when Blythe and Young Mi go sail their paper boat, they notice it sailing down the sewer. As Blythe and Young Mi looked closer, they hear It's voice. He says hello and Blythe squeals with excitements she says to Young Mi that she was excited to see a real clown. It grins evilly as he hears her say this. He says that he is happy to hear it and says that "there's cotton candy, rice and, all sorts of surprises down in the sewer. And balloons, all colors." Then Blythe and Young Mi notice It has their paper boat and as It saysthatt when they're down the sewer, they'll float with him. But as Roger arrives, the clown hides quickly as possible. Roger hugs them but Blythe was not scared, she just felt weird that It was a different and she must do something about him. Then by 4 months later, Blythe, Young Mi, Jasper, Sue, and the Littlest Pet Shop pets go down The sewer, they beat It but they see their Giant Spider form and they all do the same thing the Losers Club did 54 years ago. And by the last month later, they all went back to Downtown City. But as they went back inside the Littlest Pet Shop, Black Soldier, Jeff, and Marcus were glaring at them screaming with anger: "WHERE'S IT!?!?!?"
