Crystal Jewels/Season 1/Episode 50

The Secret Key
After the adventures of Mouselette in the last episode, Kouchu and the rest of the Crystal Brawlers are leaving to go back to Justpip Town because Shari is doing something important for them. However, Kouchu have fussed that they are suppose to be at Dark City for his fifth medal, however, Shauna and Sakuro drags him towards Shari's lab. Then, they saw that Dustin is given a big responsibility to take care of the lab while Shari is gone on an important notice. As the brawlers came by, Dustin have made them volunteer to help Shari take care of it.

Dustin have brought the brawlers in for his help to keep Shari's labortary clean by cleaning up the mess that Shari have left around it. The brawlers have cleaned up the hard stains, and have shoved many dirt outside. The brawlers and Dustin have a good time cleaning up Shari's lab, only though they have noticed that there is still a lot to clean up inside. So Dustin have Kouchu do the sweeping, Shauna mopping the floor, and Sakuro spraying detergent and washing the clothes, while he organized Shari's stuff. The mess was cleaned up, as the brawlers have looked.

However, keeping it clean shouldn't be as easy as it is than doing it with more than one person when the laboratory is falling apart. However, when they have all noticed that the building is falling apart, Plantmore have used her vines to keep it from falling away from each other. However, more of the building pieces are falling, so the Crystal Monsters Mouselette and Roaracryst sticks the pieces together so that Kouchu could glue them all back. However, the roof of Shari's house have collapsed, leaving the brawlers and Dustin into the big situation that they need to fix.

They should probably use Plantmore to stick up vines and dry the whole building up with glue, but not alone would work once the building is keep on falling into pieces. However, the plan would have been easier if Mouselette have used her rainbow powers to fix the pieces back together. However, even with Mouselette's help, the brawlers are able to put the laboratory back, and Shari came back from her big errand. After she thanked Dustin, the brawlers left and they took the bus to Dark City. As the brawlers are already heading to Dark City, the episode ends with Marcy thinking Kouchu is going to the field there, so she thinks of something.
