"What's the Roaming-Underground, as I heard other goblins talk about it and was going to ask my dads so figured you'd know." Kaley asked Crystal making her understanding knowing the Roaming Underground was a pretty awesome train that ran through the Labyrinth to other parts of their kingdom inckuding the Dragon City.
"It's a pretty awesome train like the London Underground but more cooler." Crystal said seeing an excited look on her cousin's light-blue furred face knowing she'd want to take a trip on it seeing Daphne just as curious whispering into her horned-ear making Crystal face-palm seeing them running out of her room, getting ideas plus creating magical clones of them, so Deadly and Loki wouldn't freak out packing their backpacks and had charged their phones just in case their family got worried leaving the castle.
"The station's on the outskirts of the city, let's go." Daphne told Kaley as they ran there excitedly hopingBentley and Deadly wouldn't freak out once he realised that they'd went on another adventure, reaching the station sneakingijto a train-carriage which was empty so nobody would bother them, hoping nobody back home was worried….
"Daphne, Kaley it's lunchtime, where are they." Deadly heard Loki asking making the light-blue skinned dragon male worried as Crystal, Harmomy and Melody entered the dining-room for lunch making Raven give Crystal a look sensing her daughter knew what was going on with her cousin and her variant-soulmate making Crystal sigh.
"They fouhd out about the Roaming Underground and decided to check it out, please don't be mad." she said.
"Wow that sounds awesome, we shouldtry that." Harmomy told her making Raven nervous.
"Crystal, call Casey as we need her, to drive the hydrofoil that'sin the castle." Raven told her making Crystal nodding as she used her wrist communicator knowing Casey was having a bonding day with her birth-mom Jupiter but this was an emergency knowingCasey loved adventures seeing her and Jupiter there, huggingCrystal asking what was wrong hearing Crystal explaining impressing Casey nodding as they went to where the hydrofoil was hidden so the kids couldn't takeit for a joyride seeing Jupiter wanting to come with them, seekng Raven nod as the female-tenuki was herbestfriend like Casey and Crystal were best-friends.
"Nobody tells uncle Deadly, he'll flip and never let us outside the castle ifhe findsout." Crystal told them
"Hai on that, we know he flips when Kaley doesthis, but thisis awesome." Casey told her..
