Should Yoshi have another game of his own?

Maybe...

Well he is a Magikoopa.

Yeah.

So it would be fair if he was to get the abilities of him

Yeah, I guess,

Because he wants to get Bowser back; needs Yoshi's help.

Yep.

So his story interlocks with Yoshi's, so when you unlock him as a character, you already get a vague idea of his plot.

True.

It would be awesome if Yoshi had elemental powers.

Regardless of how he gets it, I just want him to have it.

It would be fun.

Yeah, it would.

With each element, he'll change to the assigned color.

And a characteristic.

Since Yoshi has the ability to change his color, it would be better if he was the only playable yoshi besides Boshi.

His elements can solve puzzles as well as find secret areas.

Yep.

and attacks.

Of course he'll use them for attacks.

Electricty to power up nodes and unlock doors, as well as to light up dark rooms.

That would be nice.
