Cage Bombs are trickling obstacles with a countdown.
The timer counts down after every move and when it reaches 0, the Cage Bomb explodes and spawns five cages over the Jellys on the board.
The bombs can be destroyed by a match with Jellys of the same color, with Super Jelly hits and with other exploding obstacles (e.g. Living Stones, Slime Springers, Rocket Jellys).
Tip: You can use a Water Splash to clear a Cage Bomb. You can also use a Color Splash or a Color Burst to recolor a Cage Bomb.
