However, since they took the day off, Lilo, Mavis, Coraline, Guu, Audrey and Xero(who later beame the Rookie Mystery Case Files), took the job. LaCienega wasn't happy with this plan at first when Lilo rescued them with the help of Mole, Stitch and Buzzy, but she accepts it later after Lilo becomes discorded and about to give up, and she along with teh other hostages help Lilo and her friends restore their colors and defeat Discord.
It is unknown if she'll return in another mystery.
