I propose a modification to Tier 3 Blast Jellies wherein, upon death, they split into "Blast Minis" and charge at the player, replacing the Jelly Bombs thst are normally given off.
First off, I'm almost obliged to propose re-introduction of Blast Jellies' regular death explosion. But beyond that...
Blast Minis are smaller, less detailed Blast Cubes that are the same size as Royal Minis, and share the same health as the Minis in the Battle Royale level of the Jelly Palace. However, on death, they are primed to explode, and count down from 5 before doing so. They will still chase the player in this phase.
