Lily's space suit is in the building in the bathrooms, to be specific.
Where is Lily Sjoberg's space suit
DeeDah the space walrus who says melp!
Since Patton is being a bully to Dash and about to hurt him badly, Zan turns into her true alien form and brakes into Patton's mind. He scares him so much that he pees himself and runs away.
The night before the adults went out to the moon to look for Nina, the Sjobergs and Cesar were playing football with some of the astronaut helmets and they cracked some of them. Dash and Kira go out onto the moon to give new helmets to people with cracked ones, but they have to make it through a sudden hail of space trash.
The tracker computer says that Lily's suit is in the bathroom. Violet says that she heard a space walrus in the bathroom name DeeDah. The space walrus is saying "melp", and Dash finally figures out that "DeeDah" is actually Nina. Nina is under the base and crying out for help.
Chang and Dash find Nina covered in moon dust and she is almost dead. They then try to drag her into the moon base. She lost almost all of her oxygen because she was using Lily's cracked helmet.
Dash figures out that "Charlie" is Dr. Goldstein, the moon base gardner. Dr. Goldstein is very upset with herself. She was the one who sent Nina to go out and get the moon rocks. Dr. Goldstein becomes an emotional mess.
