Pizzatron 3000 was a minigame in Club Penguin Online located in the Pizza Parlor, and created by Gary the Gadget Guy. In this game players made pizzas. The game also had an alternate level Candytron that was accessed by flipping the switch on the title screen for the game.
When playing, the player looked at a sign that displayed the current order. They then made the pizza displayed with the correct sauce and toppings. If the player made a mistake then the pizza did not sell and they had to remake the pizza. Every correct pizza was worth five coins. After you made five correct pizzas in a row you would start receiving tips. Tips started at ten coins per pizza then five more for every five pizzas. If the player made 5 mistakes or 40 pizzas total the game ended.
Candytron was a secret level at the starting screen of Pizzatron that was accidentally created by Rookie. This game gave 10 coins per pizza, rather than 5. It had a few stamps of its own, but the conveyor belt was faster, making it harder.
A similar hidden candy themed game could be found in Bean Counters.
