Extra Hunting Items
In a Knuckles or Rouge level, if one of the hunting items (Chaos Emeralds, Master Emerald shards, or keys) is inside an enemy and you destroy that enemy without making physical contact with it, the item will be floating at the spot of its destruction. What's more, if you proceed to die, on the next life that item will still appear at the same spot you destroyed the enemy before! All three items will still be reshuffled and put in new locations, so in that case the remnant item is an illusion: collecting it doesn't count for one of the three you need to find, and it doesn't even give any points.
You can destroy enemies at a distance by having another one shoot it with bullets (but not lasers), letting it get caught in the explosion of a thrown or dropped bomb, digging up a bomb panel from the ground yourself, or most straightforwardly, throwing Omochao or another projectile at it.
