Level 5573 is the third level in Soft Serve Slopes and the 1155th mixed mode level (724th jelly-ingredients). To pass this level, you must clear 34 double jelly squares and release 28 gummi dragons in 35 moves or fewer.
When you complete the level, Sugar Crush is activated and will score you additional points.
There are many gummi dragons to rescue and they are trapped on a long, snaking conveyor belt that advances by one tile per move. It takes 4 moves to drop the first gummi dragon into the main play area. Rescuing 28 gummi dragons in 35 moves can be quite a challenge, on top of the need to also eliminate jelly.
The conveyor belt loops through a second portal back to its start. As the gummi dragons fill up the empty space below the end of the belt, the player must be aware that they need to keep it from overflowing. Doing so allows gummi dragons to warp back to the start of the conveyor belt, guaranteeing failure of the level as the number of moves needed to bring any back again would exceed the number of moves allowed.
The Sugar Keys can be difficult to hit immediately as they are dropped off the conveyor belt along with the dragons. They are needed to unlock the Sugar Chests blocking the drop zones to rescue the dragons.
