Official Description

It’s not a cannon, it’s a negaton pulse conversion beam. And don’t call it a haunted bottle – it’s an Erlenmeyer flask… with a big ghost in it. This LEGO Hidden Side adventure has an epic lab battle, an unexpected plot twist, and some very cheesy pick-up lines. You’ve been warned – now press play!


J.B. is scrambling around her lab to find objects while Parker and Jack are asking her questions. Finally, she shows them a Soul Artifact, an Erlenmeyer Flask that Jack calls it a "bottle", much to the dislike of J.B., as she corrects Jack. She warns them to not touch it, but Jack gets too close to the flask, bumps it, and releases Dr. Drewell.

The mad scientist begins attacking the Ghost Hunters, and they take cover. When Dr. Drewell destroys the glass to the Negaton Pulse Conversion Beam, J.B. allows Parker to use it. She is able to get it into position, but Dr. Drewell snatches it away from her and begins possessing other items. When Dr. Drewell steals Jack's phone, he demands him to get back into his bottle, and Dr. Drewell and J.B. correct Jack at the same time.

Suddenly, J.B. and Dr. Drewell stare at each other blankly. He then complements the NPCB, and both begin to flirt with each other, which makes Parker and Jack very uncomfortable. Dr. Drewell then explains that he fights for Lady E., and believes his scientific knowledge is being wasted on her plot.

After much confusion on what was going on, Jack asks about who Lady E. is, and Dr. Drewell informs them that she took over the Hidden Side and plans to take over Newbury as well. He also tells them that the Boss Ghosts were gathering Soul Essence for her and need the light next Blood Moon to release her. Jack then remembers that the next Blood Moon is the following night. After hearing mysterious noises, Dr. Drewell tells them that they must stop her before leaving.
