Rainbow Dash as an astronaut on a cloud saw Tanya Mousekewitz (Fievel’s and Yasha’s older sister) driving her space car. “There’s a blue horse as an astronaut, with a rainbow tail, sitting on a cloud, and it talks.” thought Tanya. “There’s a girl mouse, wearing her babushka, also wearing a blue blouse with a navy jumper dress, and it talks also” Rainbow thought. “Hi, there. My’s name’s Rainbow Dash. What’s yours?” she asked. “Mine’s Tanya Mousekewitz. I’m Fievel’s older sister.” said Tanya. “Uh… Who’s Fievel?” Rainbow asked. “He’s my little brother, he loves to go on his adventures.” replied Tanya. “Well, I have Princess Twilight. She is a princess of Equestria, maybe someday you’ll meet her.” said Rainbow. “and I have another friend who loves taking care of animals.” “Like who?” Tanya asked. “Fluttershy.” replied Rainbow. “she loves cute mice, someday you’ll meet her also. How would you like to hang out with me on the cloud?” “Sure.” said Tanya as she opened the glass dome of her space car. Then Tanya jumped out of her car and landed on a cloud. “Wow! I’m walking on the cloud!” exclaimed Tanya.
