Here’s part 3 of Fluttershy teaching Twilight Sparkle her underwater breath-holding skills.
 
 
Finally, Fluttershy, with bubbles from her mouth, quickly said, “Now exhale the water.” And the two exhaled the water from their mouths. Fluttershy only exhale a little bit since she’s an expert at it, yet Twilight let out a lot, getting rid of it all from her lungs.
 
“Don’t let out every bit of water out, Twilight,” Fluttershy bubbly said when noticing what Twilight’s doing, “you want to be a part of the water you’re in. So, try to have at least half and half.” Twilight was completely confused. How do you keep half of the water in your lungs, she thought. But, Twilight tried to do what she said.
 
“Now keep on doing the same thing, but pick up the speed each time you inhale and exhale the water, “ said a bubbling Fluttershy, “in no time, you’ll soon breath underwater like me.”
