Honestly, Fluttershy didn't really mind all that much. Especially as Tango - slowly, begrudgingly - started making his way down the tower, before diving into the ground.

When he resurfaced, he came up in front of Fluttershy, looking at her almost expectantly. So with a nod, Fluttershy concentrated on the spell she had learned from the books she'd read to connect with him.

And once she did, Tango started speaking in more chirps and whistles and clicks, just a dolphin would. But the meaning was clear in his mind, which made it clear to Fluttershy too.

...which, for some reason, had both her and Ballet blushing.
