Editing Destructive obstacle

The '''destructive obstacles''' include [[water]], [[fire]] and [[bomb]]s, named because they are the only obstacles which can destroy [[object]]s. Only non-moving [[monster]]s can technically be classified as destructive obstacles, because moving monsters are classified as objects.

Bombs destroy all objects; water does not destroy [[Chip]] with [[flippers]] on or [[glider]]s. Fire is more complicated, as it rejects the [[walker]] and [[bug]] and allows the [[fireball]] through, and will not destroy [[block]]s or Chip with [[fire boots]] on.

Destructive obstacles are immovable; fire is indestructible, water can only be removed by blocks, and bombs can be removed by blocks or monsters.

== Strategies for removing blocs of bombs or water ==

When confronted with bombs and a choice between blocks or monsters, note that there may not be sufficient blocks and that redirected monsters may be required to pass the requisite bombs. Also note that there may be water in the bomb stream, such that only the blocks will suffice. If the monsters are gliders, remember that you can send them over the water before you remove the water; using any other monsters, Chip would have to remove the water before any more bombs could be removed.

To remove water pools, or bombs using wholly or mostly blocks, use block pushing principles such as the rules of [[Rule of double bridges|double bridges]] and [[Rule of turning bridges|turning bridges]] and the [[Block Donut Rule]].
