Rainbow Dash was clearing the clouds when she heard Pinkie Pie calling her.
"Dashie! Come down!" Pinkie yelled. Rainbow Dash flew down to Pinkie.
"Wanna help with an experiment?" Pinkie asked.
"Sure!" Rainbow Dash answered. Pinkie then got a tank full of purple slime and put the hose in Rainbow Dash's mouth.
"I hope you're ready for a SWELL day!" Pinkie laughed. She turned on the tank and let Rainbow Dash fill up.
"MMMPH!" Rainbow Dash muffled. She was filling up fast. She attempted to pull out the hose, but failed. It locked itself in! Rainbow Dash panicked. Pinkie pie laughed at the situation. She turned up the tank. Rainbow Dash kept panicking as she tried to pull out the hose. None of her attempts worked. Her legs were starting to sink in her swiftly filling body. The tank was entering the yellow pressure stage. Rainbow Dash was filling very swiftly.
"MMMMMMPH!" She muffled.
"More? Okay!" Pinkie said as she turned up the tank more. Now Rainbow Dash was filling up as swift as ever. The tank entered the red pressure stage as Rainbow Dash flailed. A creaking sound was heard just as the tank ended the red pressure stage. BLOOOOOOOOOOOOSH! Rainbow Dash popped.
