Mickey shot thinner at Chrysalis three times. Then Chrysalis exploded and her parts whet everywhere. Then thinned into nothingness and the Changelings did the same thing right after that.
"How did you know that was Chrysalis?" asked Princess Celestia.
Mickey explained that forgotten toons can't leave Wasteland without a heart and what Wasteland was.
"Thanks for saving us from the Changelings, Mickey." said Celestia
Just then a Guard ran in the room.
He said "Princess, Discord is attacking Ponyville."
"OK, Mickey be careful Discord is the god of disharmony" warned Celestia
Then Everyone/pony whet to Ponyville to fight Discord.
