In Monster High, the two mentioned boogie monsters are Twyla and her father. Because of Twyla, we know that boogie monsters eat nightmares. We also see that Twyla can travel through shadows and see if anyone is a shadow, but it's unknown if all boogie monsters have these abilities. "Boogie Sand" can turn anyone into some kind of monster, as shown in the movie "Haunted", when it was used to turn Twyla and the ghouls into ghosts. However, Twyla's shyness does not mean she is unable to appreciate positive attention or enjoy a good laugh. It simply means her standards for feeling comfortable are higher than the average person's. Twyla is very comfortable in her own skin and embraces her freaky flaws, as well as everyone else's. At times, this means she's one of the few who can judge a situation level-headed. At others, this just leaves her feeling estranged from her fellow students. Fair and down-to-earth, Twyla is almost always about serious talking but is also very sarcastic and is the one in the group to be most likely to drop dry of dark humor since she too is playful, in a strange stoic way.

Twyla has light teal wavy hair with purple streaks. Her skin is color is a light purple, she has light teal eyesahdow and dark purple nails. Twyla is best friends with Howleen Wolf, Frankie Stein and Draculaura. She’s also friends with Lagoona Blue, Cleo de Nile, Abbey Bominable, and Clawdeen Wolf.
