What magically delicious General Mills cereal originally had four marshmallow shapes called marbits pink hearts yellow moons orange stars and green clovers?

The magically delicious cereal you're thinking of is Lucky Charms.

The four marshmallow shapes you described were:

* Pink Hearts

* Yellow Moons

* Orange Stars

* Green Clovers

These iconic shapes were part of the original Lucky Charms lineup, and while they've seen some changes over the years (like the addition of blue horseshoes and the occasional limited-edition shape), they remain a beloved part of the cereal's charm.
