— Jana to Piper in Scream Machine
Prince Fuh' Ard
Swellview Junior High
Jana Tetrazzini is a girl whom Piper Hart has a complete dislike for, and is jealous of her high number of followers and popularity.
Jana has brown hair and brown eyes. She is slightly shorter than Piper, and may be a lazy person as her father helped with her science project and did little progress herself.
Piper, as well as the rest of her family, have a complete dislike for Jana and her family; their parents may be rivals as well.
Jana Tetrazzini was first mentioned in Substitute Teacher. Piper admits her jealousy towards Jana and is furious about it.
She finally makes her debut in Season 3's Scream Machine. She's part of the Gizmo competition along with Piper and has a grander volcano than Piper's tiny one (only because her dad made it for her). She then insults both Piper and Jake and they both attempt to attack her while the other holds them back. While Captain Man and Kid Danger are trying to catch a "criminal", with everyone (including Jana) watching, Piper sneakily turns on her volcano, soaking Jana in red paint.
In Danger Games, Piper mentions how Jana has become rich by dating a prince, infuriating her and her parents' chances at becoming millionaires. She is shown briefly on TV with Prince Fuh'Ard after being announced as the winner.
