These were stored in the ROM in the middle of all of the other battle poses for the Mario Bros. (found using the currently-alpha Yoshi Magic editor). I couldn't find them on any existing sheets, but I didn't know if they were worth appending to an existing sheet.
They were right next to the poisoned and Refreshing Herb sprites, so maybe these are supposed to be Pepper effects (heavy/light, respectively)?
