The hitchhiker hydroglobes split from its ancestor, the hydroglobes. Hydroglobes grow just about on anything and everything on the west coasts of Wright. Thus when the diamiboard arrived in the waters of Wright, it was no exception. Over time it evolved a somewhat symbiotic relationship with the floating flora. The diamiboard beakworm would eat up roots of the diamiboard and eventually kill off the flora. The hitchhiker hydroglobes earn their keep by producing a sticky liquid which clouds around the diamiboard. This liquid has a duel effect, once it sticks onto the creature it will absorb into their skin and cause them to become drowsy. Thus any diamiboard beakworms which come to feed on the roots will soon become sleepy and thus do not feed on them.
Sadly this has caused a side effect urstars which cling onto the side to filter feed also fall asleep. Luckily most still hang on, but the poor few who do not have a good grip will fall off. The hitchhiker hydroglobes do not produce this all the time however. It is mainly random so the diamiboard beakworms and urstars never know when the "sleeping cloud" will hit. If too successful the hitchhiker hydroglobes may grow too numerous on the diamiboard and block out its photosynthetic crystals, thus killing its host in the process.
