Mist-Ery Guest is episode 21b of season 2 of Kuu Kuu Harajuku. .
HJ5 are going to appear on a tropical island reality tv show, but soon learn their trip is not as fun as they imagined it would be.
Rudie arrives in the rehearsal studio to tell the girls they are going to appear on a reality tv show for musical bands, on a tropical island. As soon as they get to the island and disembark, the boat that brought them there leaves extremely quickly, which makes Music suspicious.
Her suspicions are confirmed when Tizzie Lizzie arrives and announces her father bought her the tv show and the island, just so she could keep HJ5 for her own personal entertainment. Lizzie's army of robot servants surrounds HJ5 and brings them to their new home, a bad replica of a performance stage, where Lizzie will hang out with them all day long.
Lizzie brags about how nobody can get past her security system, so G offers her a challenge, if they get past the security checkpoints, Lizzie has to let them go. Lizzie agrees to the contest, because she's confident that they'll fail. Each checkpoint will only open if the correct HJ5 trivia answer is given, otherwise it will lock permanently.
HJ5 fail the first test, so have to find their way to the other checkpoints and in the process, Rudie gets lost, where is he is found by a tribe of monster pets and their leader.
Music gets Love and Baby past their check point, while G and Angel figure out the musical harmony key to deactivate their checkpoint.
Music, Love and Baby find the final checkpoint, a bridge that will fall away in pieces if they don't get a specific dance choreography from their first show right. Unfortunately, while Music and Love can remember the moves, Baby has long since forgotten them, but then G arrives and shows her the dance necessary to unlock the checkpoint.
Since they won the contest, G expects Lizzie to release them, but then Lizzie points out since she sent the boat away, there is no way to actually leave the island. Or so she though until Rudie arrives with the monster pet tribe and their handmade boat.
Boat speeds away after HJ5 disembark.
Music: Do they know something we don’t know?
G: Tizzie Lizzie? They’re letting our terrifying number one fan be in the show?
Lizzie: No siily, I’m not going to be in the show, father bought it for me. I have HJ5 all to myself again. Yay!
Music (to Rudie): You fell for another Tizzie Trap.
Rudie: No way, I was extra careful this time not to read the fine print. Oh wait, I see where I went wrong.
G: There is no way she’s keeping us here.
Lizzie’s robot servants arrive and surround the group.
G: Well, there’s that way.
Music: No-one downloaded pop? Are we in an alternate universe? Again?
Baby: Heavy Metal.
Everyone stares at Baby.
Baby: I have layers.
Angel: Country. I’m all about layering too.
Baby: I remember our first show. There were cheese puffs at the craft table.
Love: Do you remember the dance?
Baby: What dance?
