Looking like the typical Bigbom, Matryoshka-Boms have large red and gray round bodies with red and blue buttons and a face plate with blue button that looks like their eye. On top of their heads is a fuse that can be ignited. They can come in three different sizes. However, they can be considered slightly slimmer than Bigboms.
Matryoshka-Boms come in three sizes. The large ones normally walk around back and forth in gameplay. Upon encountering the player however, these Badniks will act like a "matryoshka doll"; the large Matryoshka-Bom will open its mouth and release a medium-sized version of itself before lighting its fuse, who will then release an even smaller version of itself before lighting its own fuse. A few seconds afterward, these enemies will explode, each of them releasing four large projectiles that rain down around themselves.
Regular and smaller sized Matryoshka-Boms also appear around their Zone on their own. While regular-sized Matryoshka-Boms can drop smaller ones on their own, the smaller Matryoshka-Boms function as a regular Bomb from the original Sonic the Hedgehog, though with a much faster walking speed. Unlike many other Badniks in Sonic Mania, Matryoshka-Boms do not release any Animals upon their destruction.
↑While not listed in any instruction manuals, the internal files in the PC release of Sonic Mania refers to this enemy as "MatryoshkaBom".
