Bowser's Sourpuss Bread

"You know what they say: all toasters toast toast!"

- Mario

Bowser's Sourpuss Bread is a brand of bread that is used in Hotel Mario. As well as its name being on the product in green text, the blue packaging includes a logo of Bowser's head, implying that Bowser's forces manufacture this bread. It is toasted by too many toasters in Roy's HardBrick Hotel, where it causes electrical flickering.
