Popcorn is a common blocker in CCS fanons. It is a strong blocker that occupies one space and takes three hits to remove.
When it is hit by a special candy, the popcorn grows larger on the square upon which it sits. When it is hit a second time, it grows even larger and starts flashing. When it is hit a third time, it pops and reveals a color bomb that can immediately be used by the player.
Unlike most blockers, popcorn is immune to adjacent matches. Also, popcorn blocks the effect of striped candies and their combinations, just like licorice swirls. If a striped candy's effect hits a popcorn blocker, it will increase the size of the popcorn as described above, but the effect is blocked, so none of the candies beyond it are affected.

This blocker first appears at Level 421 in the 30th episode, Popcorn Palace. It is a fairly common blocker, and most episodes after their introduction have at least 3 levels with popcorn, with each level in Popcorn Palace having at least one. Unlike the original game, hitting it with a lollipop hammer will grow the popcorn by one layer.
CCJS
Popcorn appears for first time in the 53rd episode, Popcorn Park. The first level in which they are featured is Level 771. Like Candy Crush Saga, jelly fish avoid popcorn, even when there is jelly underneath the popcorn. At the last stage, if a striped candy's effect hits popcorn, candies beyond it are not affected.
