Pinkie Pie and the Wiggles went to a castle that looked sort of like a purple tree.
"This is the castle where one my friends who's also the Princess of Friendship lives. My friends are waiting for us inside. You're gonna love them!" said Pinkie Pie.
"Well alright then. We're ready!" said Greg.
Pinkie Pie led the Wiggles to a big room with six chairs. There were five other ponies and a purple dragon sitting in the room and talking.
"Girls, this is the Wiggles. They're a children's band from another universe that ended up in Equestria after they fell through a black hole." said Pinkie Pie.
"Uh Pinkie, are you sure they aren't changelings disguised as humans from the other side of the portal?" asked Twilight.
"Trust me Twilight. They told me they mean no harm and just want to be friends with us." said Pinkie Pie.
"Pinkie is right. That fact that we ended up in your world was a total accident. If you don't believe us, we'll perform one of our hit songs for you and any other royal subjects." said Greg.
"Fair enough Sugarcube, It's a deal." said Applejack.
"Applejack is right. I'll go get Princess Celestia and Princess Luna." said Twilight and she went to go get Princess Celestia and Princess Luna who were waiting just outside the room.
******************
About a minute later Twilight came back with Princess Celestia and Princess Luna.
"Ok creatures from another universe, you must prove that you aren't changelings disguised as humans. I want you to sing your best song. If we like the performance, we'll let you stay in Equestria unbothered until you figure out how to get back to your universe." said Princess Celestia.
The Wiggles huddled together to discuss which song they wanted to perform for Princess Celestia and they decided to let her choose which she wanted them to perform.
"Ok we'll give you three choices of what song we'll perform. Choice number 1 is the Fruit Salad Song in which we need one pony to sing a small part in. Choice number 2 is Hot Potato. Lastly, choice number 3 is Rock-a-Bye your Bear." said Murray.
"How about the Fruit Salad Song." said Princess Celestia.
"Fair enough. Great choice!" said Greg.
"Hey Pinkie, we need you or one of your friends to sing a small line in this song." said Anthony.
"Hey Fluttershy, you're probably the best singer in room. How about you help our new friends out?" said Pinkie Pie.
"Oh my. I wasn't really expecting this but I'll do anything to help prove these creatures are innocent." said Fluttershy.
"Ok Fluttershy, all we need you to sing is 'Yummy yummy yummy yummy Fruit Salad' when I give you the cue." said Anthony.
"Ok. Let's get this over with." said Fluttershy.
******************
Right after the Wiggles along with Fluttershy were done singing the Fruit Salad Song, Princess Celestia was in absolute awe.
"I can't believe I'm actually gonna say this but, that was the best singing I've heard out of anyone. You and Fluttershy sounded great together!" said Princess Celestia with a smile on her face.
"Hey, we're the greatest children's band of all time for a reason." said Greg.
"Hey guys, Applejack's sister is having a slumber party at her house with her friends tomorrow night. I think they'd love to have you guys there and to hear you sing." said Pinkie Pie.
"We'd love to perform for Applejack's sister and her friends tomorrow night." said Jeff.
"Alrighty then let's do it. See you at Sweet Apple Acres tomorrow night." said Applejack.
"Hey guys, you can sleep in my castle tonight since I absolutely enjoyed hearing you and Fluttershy singing. You deserve the absolute best treatment while you're in Ponyville." said Twilight with a smile on her face.
"Why thank you. We're absolutely honored to be sleeping in the castle of one of Equestria's royal subjects." said Greg.
"Good night guys. I'm really looking forward to hearing you sing more tomorrow." said Twilight and she and the Wiggles went to bed.
