Should Yoshi have another game of his own?

Yeah.

He could discover secret passages and other kinds of secrets.

Do you think he should get vehicle powerups, costume powerups, or monster powerups.

Not really.

He doesn't need all of those power-ups.

Monster powerups.

What would that do?

i loved the powerups in yoshis island, if there is a 3D yoshi game then they definitely need to be back

Transform yoshi into a monster, for a short time, like to tunnel underground he becomes a Monty mole, he is still green, but as the monster for about 30 seconds lets say.

He doesn't need that.

He'll transform into a digger instead.

In fact, the digger looks exactly like a mole.

Pokey to hide under sand, and to shoot needles, as well as use to stand on tile panels.

He doesn't need that.

He doesn't need to tranform into any monsters.

Shame.

It would be pointless for him to transform into all of those monsters.

I only named 2.

I'm sure that you had more in mind, right? 😉

Yeah, you got me.

😎 I know.

Cool.

What are some more abilities/attacks that Yoshi had in the previous games in which he could use in this game?

....I don't know.......hmmmmm......nope......nada........*retreats off to update my Super Mario Wiki page*
