[...His thought process. Right.] Feraligatr is well rounded. Good offensive and defensive strengths... But he's pretty heavy, so he only has good speed in short bursts and in his reflexes. That's why Earthquake and Surf are good moves for him.

We've practiced with Surf a lot to make it wider or narrower before. Since Explotaro's pretty fast, it seemed like a good idea to narrow that water pressure even further to get Feraligatr to move a lot more quickly. I'm not sure why I didn't think of it sooner. Aqua Tail just followed suit. My big sis came up with something pretty similar before to quickly maneuver in the air with her Blastoise.
