Love Hearts is a type of item that Four shoots out of his eyes and mouth when he sees something he adores.
Four screeches for (at least) 2 reasons: the first is when stunning and/or harming a contestant, or when he likes something. The hearts themselves are solid, thus they can hurt someone. Eraser was hit by a heart and flung through the sky, while screaming. The second appearance the Love Hearts made was during "Today's Very Special Episode", where there were roughly 345 hearts shown.
Woody arguably used them with Teardrop in "Take the Plunge: Part 1".
Trivia
- They are red in BFDI 1a, however in "Today's Very Special Episode", they are pink-ish red.
- The love hearts have only appeared twice: once in BFDI 1a, and again in "Today's Very Special Episode".
