Finally - the Rare Shellbeat has been revealed! This especially bashful being only emerges once in a blue moon, so great care must be taken to make sure it feels welcome among its fellow monsters. Once it's settled in a jam session, the Rare Shellbeat has been known to produce pearls of exceptional quality from its unique shell, which it gives away as presents! This curious quad-element often contemplates the nature of the monster world, and the possibility of alternate universes. If it's learned anything, it has so far decided to keep the secrets to itself.


The Rare Shellbeat is blue, suiting the habitat in which it usually lives. The spots are now a lime-ish green. Also, the webbing in between its fins and the fins on its arms are now black. In between its two shells is a gray-ish purple color. It has the same types of limbs, belly and face, although seen in blue hues. Its head is now quite cephalopod like, being that it is now more cone shaped, and even has squid-like fins near the tip of its head. There are also quite a few sea stars on the monster, on its shell, and some on its drum kit.

One of the more noticeable differences is the bivalvial shell instead of the normal univalvial shell. Another difference is that the drumkit is also more yellowish than the normal Shellbeat's drumkit. Seen on its head, there are now also visible gills just above its head fins. When observed carefully, the symbol on the drum is a different pattern - the same pattern as the Runic Path on Ethereal Island. witch may show a connection with the ethereal realm even though they're natural.

The Rare Shellbeat's contribution to an island's song is a collection of mid-to-high pitch percussion sounds. In addition to its drumset and cymbals, the Shellbeat also uses its own shell as a drum. It plays on the drumset using the sticks in its hand while playing its shell with its tail. Its shell plays the role of producing the bass drum of a drumset.


The Rare Shellbeat can be bred using monsters that combine to provide all the elements Plant, Air, Water and Earth without repeating any.

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

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

The Rare version of any monster can be used for breeding instead of the common version.

It is possible to breed a Rare Shellbeat and a regular Shellbeat togegther.  The outcome will always be a Shellbeat, and if a Rare Shellbeat is available at that time, it may result from this combination.

Feeding Monsters

Each monster needs to be fed four times before it reaches the next level. Increasing the monster's level increases the coins earned per minute. The food per level is the same for all four element monsters and can be found in this article.


  • Stritch SkinGo to Stritch Skin
  • ShellbeatGo to Shellbeat
  • Crumpler TreeGo to Crumpler Tree
  • Leafy Sea DragonGo to Leafy Sea Dragon

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 Shellbeat:

See the Likes page to view a complete list of all monsters' likes.


Some items to take into consideration when designing your island by strategy are number of beds for the monster, rate of income per bed, max income per bed, and time for max income to be reached. The income below is for level 15:

Number of Beds 4
Rate of Income High 330
Rate of Income Low 165
Max Income 194.700
Rate of Income per Bed High 82
Rate of Income per Bed Low 41
Max Income per Bed 48.670
Time to Max Income @ High 09:50
Time to Max Income @ Low 19:40

Name Origin

Rare Shellbeat might be a compound word of shell and beat, because of the monster's mollusk-like shell and the fact it plays drums during its active periods in-game.


  • This Rare Monster is the 6th-to-last (check?) Natural Rare Monster to be released.
