If you thought that only "The Player/Avatar" had their own 2 Challenge Modes... Nope!
There are also a building Challenge Modes in the Pizzaomnia!

(There are 3 in total, but now I will introduce one building challenge mode to you)

The first challenge mode in the building is where there are
set around the traps of type: The Pipes and Wooden Blocks.

The Sunplant Piranhas and Golden Chompers can attack Silent "The Player/Avatar" and try to swallow her to "Eat" aka. the "Stamina Core" that she has.
Then they spit her out and she is stunned for a moment.

The "Stamina Core" counts 7 bars. If they are all eaten...
Silent "The Player/Avatar" cannot use the Items!
From some time, the bars will charge to their fullest.
After the recovery of 7 bars "The Player/Avatar" can use Items again.

Hope you like this idea.
