Black hole

Temporal Black Hole is an exclusive Brain Buster played in Kung-Fu World where it is a Last Stand level, but has its own gimmick where a black hole will appear at the end of certain waves. They appear in Days 15, 20, 23, 28, with a special gate using keys to unlock with three levels of them.

When the black hole is about to appear, a message will appearing, saying, "The temporal black hole is about to absorb your plants!" The black hole will always appear at the first lane from the left, and will move all plants one column to the right. Plants which are placed at the column where the black hole appears beforehand will also be sucked in. Both planting and recharging plants are disabled when it appears and can only be done when the hole completely disappears. The hole's pulling force can be blocked by White Radish.

Strategies
Whenever playing these levels, it is highly recommended that you always bring White Radish, as without it you may risk losing your plants either by the hole or being eaten by the zombies, since the plants will be pulled closer to the horde. Plant a whole column of them to be safe.

Avoid planting Spikeweed and Spikerock, as they have to be planted in front of the White Radishes to be used properly, which make them vulnerable to be sucked in. Do note that unprotected chestnuts from Small Chestnut Team can also be pulled.
