Keldeo's Secret

"S-Sophia, the voices speak again." Keldeo stammered at Sophia's mat. Her chest heaved once, then again...then her eyes fluttered open.
"Keldeo, are your parents rambling about the Chaos Crystal again? LaSalle is the only one who has the passcode to unlock the Chaos Cavern in Vramaa, as her mother once was a general in the Vramaasian army, so just wait until she comes back with the heart." Sophia said. Keldeo sighed.
"But Soooophia, Soapy, this time they said that I need to power up before the heart enters this dimension, else all the effort will be worthless!"
Sophia sighed, and got up.
"To be nice, I'll get up, but at least try to work on stabilizing your hoof jets, 'k?" Sophia said. Keldeo nodded, and he used his best powers to teleport them to Cosmo's greenhouse.

"C-cold..." Keldeo muttered.
"Well, this will be a practice setting where you actually have to keep moving to keep the jets up. We tried staying in your stable idle position, and the ice corroded your hooves. It took Cosmo a lot of aloe paste to heal the cracks, and aloe is scarce in Jamaa." Sophia said. Keldeo was clearly a master of water, so the Winter section of the greenhouse was his nightmare.
They kept walking for a while, Sophia sometimes stopping to point out some musical icicles she wanted Keldeo to play to open up a snowy path.
If you had never been here before, you would wonder why they ventured into the heart of the section, but all of the seasonal sections had a small pond in the middle, connected magically to the fountain in the heart of the greenhouse. They said that they contained the power of the elements.
Suddenly, a yeti hopped out from behind a mighty redwood. Keldeo had no idea if redwoods could survive at this temperature normally. Of course, Cosmo was the alpha of plants, so his magic could alter the DNA of any plant, as long as it was willing for the change.
"Hypnoti, pernamate." Sophia said. The yeti yawned, and sleepily lumbered away before it could notice them. Cosmo was nice, but for some reason he let dangerous monsters rent some territory from him.
"I say that this is a sanctuary for flora and fauna, and my magical plant servants keep them stuck in the patch of land I give them." Cosmo had assured Keldeo when the little colt had learned of this disturbing detail.
Even more walking. And more.
Not-so-soon, they reached the spring. It was iced over, with frozen plants at the water's edge, but etched in the ice was an image of Mira and Zios doing sex, but Zios's penis was faint due to his body masking. Keldeo really wished that the image was suitable for the eyes of a colt.
"Do your jets on the ice, there is something underneath." Sophia advised Keldeo. The little colt was shaky, but trotted onto the surface successfully. Then, he willed his hooves to spray water.
The jet of water resulting blasted Keldeo upward, and he barely could manage to keep the water going as the ice melted.
Underneath the thick ice, was a small Sea Heart. The magical heart of blessed water floated upward, attracted to Keldeo's horn. The colt kept the jets up, Sophia watching.
Keldeo watched the Sea Heart slowly come forward...and BAM, Keldeo suddenly started to sprint across the treetops with stable jets, Sophia unable to keep up.
