I know some of these might look a bit different and some may not even be in the game, but I figured since the official game had hundreds of different items and fruits so I thought as long as all the originals are present then there could be any random things available.
The green fruit is more than likely a Breadfruit. It's a tropical fruit, and doesn't exactly show up in everyone's home town. It's been used in many games though and since it's not labeled properly it's often called a melon.
I did check out the game play of Pac-Man CE and man the challenge is definitely there, for anyone who wants it.
