Level 664 is the fourteenth level in Fizzy Falls and the 148th ingredients level. To pass this level, you must release 5 gummi dragons in 21 moves or fewer.
When you complete the level, Sugar Crush is activated and will score you additional points.
The bubblegum pops blocking the dragons are under sugar chests. Keys must be used to clear the pops tha are blocking these dragons, and one key spawns for every two moves. This means that this level cannot be completed until there are 11 moves left.
Five colours make it hard to clear the blockers for the dragons.
