Dipsters are a set of seven Monsters that each only play typically one note of the musical scale, hence the names Do, Re, Mi, Fa, Sol, La and Ti. They pop up from the ground each time they sing a note and every note is a "dip," singing a certain pitch depending on what their name is. They also have different natural items on their heads.
All the Dipsters sing "dip," but with differing pitches depending on which Dipster they are. Do typically sings at the root (first note) of the scale, with Re typically singing the second note of the scale, Mi the third note, and so on for Fa, Sol, La, and Ti. The Dipsters behave like handbells, where one sings each note, each Dipster being a different bell.
My Singing Monsters your best friends!
