Star BitsEdit
You can break the boulders by spinning the red spot, but only the first three times you do this, you are given Star Bits. After that, nothing. Chomps in the games act similar, but their Star Bit supply gradually runs down from 6 about 5 times, to 1 about twice, then nothing. I am not trying to say Boulders and Chomps are related.

Wario LandEdit
Is there any official source that says the "boulders" in Wario Land: Super Mario Land 3 are actually boulders? The non-spiked ones look to me like giant berries, and the spikes ones just seem to be spiked balls.
