It can only be used for good reasons by cleaning things up. So far, we can understand squids and octopuses don't like the reef blower, until Squidward Tentacles likes the reef blowers.The only people seen doing the reef blower is SpongeBob, Patrick, Squidward, and the Groundskeeper of Tentacle Acres. Also, it uses a long, long brown or black wire with a red sucking hose. It is connected to a DustBag which is white, has a red top, has a filter, a cartridge filter and attachments. It can blow and suck things. Reef blower hoses attach to the reef blower.
