Only when their thicc booties collide do they go into arousal overdrive, leading to the creation of Fresh Care, a queen who has a nice pair of flanks to back up her authority.

As was previously stated, the fusions have their own personality; influenced by, yet still separate from, their component mares. They’d have memories of those their component mares knew, however. So no, the fusions wouldn’t know each other, outside of a passing familiarity. The reason King Speedy Hooves knows his wife’s freaking out over research as her ‘Twi Mode’ because he was there to see Galaxia’s fusion.
This is probably the most interesting personality wise. Minuette is almost as perky as Pinkie, Mayor Mare is this wise authority figure, and Derpy is… well, Derpy. (We don’t know Carrot Top that well, do we?) How does that go together?
But of course, her being a fusion of four mares would of course have to pack all that extra mass somewhere, and where better than her assets.
Fingers crossed she’ll regain her knowledge in at some point then.
