Aurora Block

The Aurora Block is a powerful, rainbow-colored block used in Mario & Luigi: Partners in Time. It is notable for its ability to grow the size of the heart of the person who strikes it, and its very existence is celebrated in the Star Realm.

During the events of Mario & Luigi: Partners in Time, Mario, Luigi, Baby Mario, and Baby Luigi find a talking gate at the Star Shrine who tells them that they cannot continue unless he "reads" them to see if they're worthy or not. Although courageous Mario passes the gate's test easily, chicken-hearted Luigi is not as fortunate. The star gate gives them three options: go home and eat some pasta puttanesca, continue without Luigi, or find the elusive Aurora Block.

The team quickly chooses the third option and sets off to find the ominous Block. The quartet discovers it quite easily, but Luigi finds himself unable to hit it. The gate then asks Luigi who did the work of finding it: Mario, the babies, or Luigi himself. Ironically, the correct answer was the whole team, which wasn't even a choice. The gate then dubs Luigi a liar in addition to a coward and becomes quite a nuisance, driving Luigi to the point where he cannot hold back his tears. Mario then tells the gate it was lying itself and Baby Mario attacks it with his hammer.

After that, the Star Gate reveals that this was all just a test to find out the greatness of their brotherly togetherness. He then gives them the titles of "best brothers in the world" and tells them that they're all ready to proceed to the rest of the Star Shrine. Best of all, the gate lets the confused Luigi hit the Aurora Block, which he does hastefully. However, it is then that the gate chooses to tell Luigi that the Aurora Block can grow to the size of the heart of the person who hit it, and, after he says this, the block turns gigantic and squashes him.
