Flitter with a Gem

Flitter's Tip

Butterflies are your allies! Please don't eat us. Also, you will usually only see me every 10 min or so - it takes time to collect pearls and gems for you. They're so heavy. Do you have any pancakes? Or can you help me?

A Moment of Math

If you use Poison Cloud as your Smokescreen talent and you have Shadow Swarm active, you are missing out on a significant amount of damage. Almost 25 times the Shadow Swarm multiplier to be exact. Read the Smokescreen article for more.


Version 3.4.0 Available - Welcome to the Abyss

Version 3.4.0 brings a much needed change to Land of Reptiles, and introduces a brand new aspect guaranteed to make tournaments more stressful for players that want to tie for 1st.

Land of Reptiles is no longer limited to 10 difficulty levels. After defeating the 10th difficulty you are promoted to a new "Tier" with 10 more difficulty levels. If you had previously beaten all 10 levels in the old Land, you will start in Tier 13 with this update.

Each tier adds power to the new visitor to the riverbed - the Abysswyrm. Abysswyrm has a chance (2.5%) to appear in place of a boss. If you defeat the boss you instantly warp forward a distance. Every Tier in Land of Reptiles adds +10m to this warp distance. Tier 13 (where most veterans will start) is +140m.

Claw of Midas buff now also increases Abysswyrm's chance to spawn in addition to the + to reptile gold. If you watch 2 additional ads your Abysswyrm will gain +2% chance to spawn.

The concern in tournaments is getting an Abysswyrm when you are trying to tie and leaping 100+ meters past the tie point and causing chaos.


In addition, a new event has started for Carnival (south american festival) that is identical to most other events. Collect special items from the event butterfly and unlock a prize tree, including a new skin for AppX crab. As usual there is also a promotion to buy gem sets, conches, and additional skins.

Version 3.3.0 Available

New version in preparation for the Lunar New Year event coming soon. Some much asked for Quality of Life improvements have come as well in the form of being able to abort the conch opening animation, and buying multiples of Abilities and Mutations. There is also a new Power Saving mode.

One thing to note is your total DNA is no longer displayed as a full number but rather in Crab War Notation. This makes using our Spending DNA optimizer less accurate. I've reached out to AppX to fix this or give a toggle or something to see the full number again.

If anything about the Event is different than usual events, we'll update this once we know. Happy 2019, Pig Crabs.

Version 3.0.0 Available

A "MAJOR" update, per the release notes, introducing a monthly event that was promised earlier this year when Pearl Hunter was removed from the gene tree. AppX said they would be introducing an event to help players earn pearls again, and this is it.

For six days you get to collect rune fragments from green fireflies that appear every 20 seconds in the main game. You earn Runes by getting enough fragments. The Runes appear on a 10x10 board like Bingo. The more Runes you have, the more fragments you need to get new Runes. As you complete 10 Runes in a row (horizontal, vertical, or diagonal) you are given a bonus of pearls, gems, genes, or a free Burrower Crab.

After the six days is up, presumably the board locks and the Jade Scarab joins you in addition to the Rune bonuses going active.

There is a Library Article on the subject as well as a new worksheet.

Butterfly Arcade

We moved all of the silly mini-games into the Butterfly Arcade (under the Info menu) so they can be found easier. At the same time we added a new game specifically as a thank you to school sponsors: Benny For Hire. Ever have a desire to turn the tables and help the reptiles? Consider supporting the school.


A couple people have said we should have a Donate button. We do. Visit the Info menu to go to our information page where you will find an option for a one-time donation as well as becoming a Supporter through Patreon for recurring donations.
