🐉Dorsal

Part of their physical attributes

The tail is a key piece of a koin, and they come in many different forms. Its upper fin, in addition, always matches its tail. We call the set of both elements the dorsal.

Bonnet

This type of dorsal is the most common among the koins, providing just enough technique to let them show off at races.

Brush

With this common set of larger fins and tail, koins with these features are ready to paint their rivals' defeat.

Beak

Similar in appearance to that of a mighty bird, this tail appears to start and end at the same time. Makes for a fantastic set with its upper fin.

Bow

A rather uncommon sight, this elegant dorsal is simple, yet makes a statement.

Blade

Don't swim near this rare tail, or you might wind up cutting yourself on its sharp appearance. Also, watch out for its upper fin!

Bait

With this rare dorsal, the lure becomes the lurer! So small, yet so powerful.

Bellows

This rather rare back is a spectacle anywhere it goes, leaving in its wake, a trail of admiration.

Blackfly

While it’s completely harmless, this particularly rare stinger of a fin makes opponents think twice before trying to pass.

Basil

Only a small batch of koins come with this particular back, which seems to leave a sweet scent on any track it’s displayed.

Bight

Commanding glances anywhere it goes, this set brings up an immediate urge to surf whenever it’s seen. Cowabunga!
