Algea is a form of hallucinogenic micro mushroom which favor moist conditions and grown esp in Florida by hardcore drug users,
when planted on a cars soft top roof, the root system penetrates the covering and grows towards the next moist area – normally the drivers brain, which it will then invade and quickly convince the driver via it’s mind alternating substances, that he is having a great time driving around, swimming, going to nightclubs, dancing with beautiful people, surfing the web and having conversations with interesting people while the
whole time the “victim” is actually sitting drooling in their car.
Or it could be Algae which is a kind of seaweed, please note that the same effect can be achieved with Algae, which once dried, can be smoked.
At least this is what some Cracker told me as he sold me some wet soggy seaweed.
