Pokémon mystery dungeon

What have you done!

Cocoa had the gem in her grasp but howl and jasper came in to check on her because she was gone all day long...
Star told them she was just being an addict but they didn't leave.
"This is the girls dorm room... do you want to get pestered." Cocoa tried to ward them off with that... but they were too loyal.
"Heh... heh... heh..."
What was that!!! Cocoa thought.
Cocoa looked around... but no one else had heard the voice.
"So nice of you to gather them all in one place... SO I CAN END THE WORLD!!!" The gem was turning black and with her friends Cocoa made the five hour walking in roughly 8 seconds... impossible right...
"Help me lily! The gem is dying and the world will end if it does!!!"
Lily ran over and so did a couple of other Pokémon.
"We heard about the gems from our dreams... and we have came to overpower the black being."
"He has a name."
"Then what is it."
"I forgot."
They all pressed the gem and the movement of the black part stopped.
"We need more Pokémon! Fast! If we don't... we will die soon! And so will everyone else!" Cocoa yelled.
Howl, jasper, and Star all ran out to find more people by asking. "Did you have a dream that took place in a field with a gem... if so come with me!"
Soon they got back with a few more Pokémon and used their power.
The Pokémon were half dead by the time this was done... but they were pretty sure jerry was dead... at least for now...
*yup hello... jerry will never die because I have no other plot... no i will not add I romance plot between Cocoa and someone or Star and someone... I'm just mocking that... nothing romantic involved between them.*
