Found much less frequently than the common Riff, this Rare Monster nonetheless offers great insights into the habits and behaviours of this secretive species. For instance, it's now known that all Riffs share a symbiotic relationship with their guitars, which are actually living creatures as well! Riffs exchange the foods they collect with their toes for whispered messages of affirmation about their musical performances. Go team.


The Rare Riff is a green monster with three toes per foot, a violet mohawk, two pairs of wings of a bat, and traces of feathers on its body. Its has two rings on each of its feet, while its claws have one ring on each "index claw". The wings are also somewhat larger than the common counterpart's wings, and also are in pairs.

The Rare Riff, like the common Riff, has a guitar monster that shares symbiotic relationship with each other, but has physical differences from the common Riff's guitar monster. It is more rectangular, with an eye at the top and a "mouth" that appears on the bottom of the guitar. It is also orange with spots like the skin of the common Riff. Its guitar resembles the head of a Tyrannosaurus rex.

The Rare Riff Monster's contribution to an island's song is playing an instrument resembling an electric guitar. The guitar is not actually electric, nor is it a real instrument; it is another monster that shares a symbiotic relationship with the Rare Riff. The guitar monster produces sounds matching its real-life counterpart.


The Rare Riff can be bred using monsters that combine to provide all the elements Cold, Air, Water and Earth, just like its common counterpart.

The following pairs of 2-element monsters can be used to breed a Riff:

However, the combination of a 3-element with 1-element monster has higher rate of success for getting a Riff instead of one of the parents as the outcome:

T-Rox and Tweedle have the shortest incubation times, giving another chance to breed the monster more quickly than any of the other 3-element + 1-element combinations.

The Rare version of any monster can be used for breeding instead of the common version. Also, it's possible to breed a regular Riff with a Rare Riff, and the result will always be another Riff.

Every monster has different things that they like. For every unique object that they like that's placed near the monster (if not using a Unity Tree), the monster's happiness will increase by 25%. Placing two of the same liked item near a monster will still only increase happiness by 25%. Below are the things liked by Rare Riff:
