It’s hinted at the very start that ICE-ERAM was Pizzarina the whole time due to the disturbing pizza-related presence ICE-E always had on the Lightners and Jevil flat out warning you about Nightmare (ICE-E) being a legitimate threat to you in the light world, not in the dark world.

The moment that she was established to love Pizza and is heavily identified by this, I knew instantly that ICE-E was somehow behind this. Since the vast majority of Pizza references are almost always connected to ICE-E, demonstrating how abnormally obsessed the ICE-E entity is with Pizza. That Pizzarina has this significant distance between every lightner tied to her besides for the most cultist ICE-E fans that share this fascination.

Also remember that the pizza-related JPEGS belong to “ICE-E’s Pizza Pinups Mangazine”. So, for how stupid Pizza Pant’s descriptions for what the JPEGs are in his eyes, it perhaps is revealing that these are actually ICE-E’s/Pizzarina’s pinup pictures and her limitations are due to her nature of being a Darkner depending on Lightners to interact with the Light world. And this is the only time when ICE-E and Pizzarina are implied to be the same entity by them having the same pizza pinup pictures.
