After they entered the firehouse, they were amazed to see the inside looks nice. Then they noticed Henry's car, the Ecto-1 'What is this weird looking cart ?' 'Oh this is not a cart it's my car, a car is a type of transport humans use to go on journeys on roads more easier and anyways this is Ecto-1 and I used it when people called saying they got ghost troubles and I used it to get there' Twilight was impressed 'Amazing, but um...' she notices the muon trap 'What is that thing on the roof ?' she motioned a finger to the muon trap 'Oh that is a new trap I invented, it's called Muon trap 'aka' Super slammer it can catch ghosts a lot more faster compared to my portable units' Henry explained then they went down to the basement and saw the containment unit 'Woah' Twilight said in amazement 'What is that ?' 'This is my ecto-containment unit, it's where I stored the ghosts I caught' then he opened the slot and insert the trap and closed it, pressed some buttons and pulled down the lever until the light's above the unit turn red to green signaling the trap is empty now' then they went up to the lab, 'This is my lab, it's where I create new equipment' then he showed them the PKE meter 'This is my PKE meter, it register's psycokinetic-energy readings to tell there or was a ghost in the area' then they head back downstairs. Princess Celestia was impressed until she had an idea and motioned Twilight and her friends to come towards her, then they whispered so that Henry can't hear what they are saying. After they were done, 'Henry, the princess wants all of us to go to Canterlot' 'Canterlot ?' Henry asks Rarity giggled 'We have a special surprise for you' then Princess Celestia lit up her horn and trnsported them to Canterlot.
