Shells Database
The Shells Database is the main reference page for tracking shell types, rarity groups, farming locations, route notes, collection priorities, and value planning in Roblox Shells. Use it as a practical checklist when you are trying to decide what to collect, where to farm, and when to move from one route to another.
All Shells in Roblox Shells — Sorted by Rarity
Every shell in Roblox Shells has a rarity tier that determines how often it appears and what it sells for at the Merchant. The value shown is the base price per kilogram before any mutation multiplier. Mutations can dramatically increase the sell value — the rarest mutation (0.01% chance) gives an 8x Shellings multiplier, and the Scorched Mutation from Eclipse events gives 1.7x. Here is the full confirmed list of shells organized by rarity.
Bay Scallop, Common Cockle, Barnacle Cluster. Found everywhere, especially Bay Island. Good for learning the dig loop.
Sand Dollar, Sea Glass, Cowrie, Noble Scallop, Clam, Babylon, Sundial, Dubious Volute, Volva Volva. Appear across multiple islands.
Conch, Nautilus Shell, Mitra Mitra, Worm Snail, Lightning Whelk, Tusk Shell, White Abalone. Need better gear and specific islands.
Mythic and Exotic tier shells appear at late-game islands. High mutation chance on these means massive payouts.
Common Shells
Common shells appear on nearly every island and are ideal for new players learning the digging mechanic. They are low value individually but sell well in bulk.
| Shell Name | Value (per kg) | Rarity | Islands Found | Description |
|---|---|---|---|---|
| Bay Scallop | $25 | Common | Bay Island, Crescent Shore, Caldera Cay, Sea Stack, Nautilus Hollow | Small fan-shaped shell found in shallow bays. Ridges shine in sunlight. Easiest shell for beginners to find. |
| Common Cockle | $15 | Common | Bay Island, Crescent Shore, Caldera Cay, Sea Stack, Nautilus Hollow | Ridged shell scattered across sandy shores. Simple but charming. Most frequently found shell in the game. |
| Barnacle Cluster | $25 | Common | Solmere only | Dense rosy-pink cluster of fused barnacle cones. Rough to the touch. Found exclusively at the endgame island Solmere. |
Uncommon Shells
Uncommon shells are worth slightly more and begin appearing on Crescent Shore alongside Bay Island. They are a good sign you are progressing through the early game.
| Shell Name | Value (per kg) | Rarity | Islands Found |
|---|---|---|---|
| Sand Dollar | $38 | Uncommon | Bay Island, Crescent Shore |
| Noble Scallop | $34 | Uncommon | Bay Island, Sea Stack Islands |
| Sea Glass | $48 | Uncommon | Bay Island, Sea Stack Islands |
| Cowrie | $60 | Uncommon | Bay Island, Crescent Shore |
| Dubious Volute | $68 | Uncommon | Crescent Shore, Caldera Cay |
| Sundial | $71 | Uncommon | Bay Island, Crescent Shore |
| Clam | $41 | Uncommon | Bay Island, Crescent Shore, Sea Stack Islands |
| Babylon | $41 | Uncommon | Crescent Shore, Sea Stack Islands, Caldera Cay |
| Volva Volva | $66 | Uncommon | Solmere only |
Rare Shells
Rare shells begin appearing more frequently at Sea Stack Islands and Nautilus Hollow. The Conch is notable because it is required for the Hermit Crab companion system — equip the best Conch you find to boost your Hermit Crab's offline bonuses.
| Shell Name | Value (per kg) | Rarity | Islands Found | Notes |
|---|---|---|---|---|
| Conch | $82 | Rare | Bay Island | Equip the Conch to your Hermit Crab to boost its passive shell collection bonuses. Always upgrade to the best Conch you find. |
| Nautilus Shell | $82 | Rare | Nautilus Hollow | Exclusive to Nautilus Hollow. The island is named after this shell. Good reason to unlock and farm this area. |
| Mitra Mitra | $90 | Rare | Sea Stack Islands, Nautilus Hollow | Slender pointed shell with bold geometric banding. Good early rare shell target at Sea Stack Islands. |
| Mitra Stictica | $94 | Rare | Sea Stack Islands, Nautilus Hollow | Similar to Mitra Mitra but dotted with fine speckles. Slightly higher value. |
| Worm Snail | — | Rare | Sea Stack Islands | One of the most searched shells by name. Requires Sea Stack Islands access and decent tool luck to find consistently. |
| Lightning Whelk | — | Rare | Sea Stack Islands | Highly sought after by collectors. The Frosted Tideclaw or better is recommended for reliable Lightning Whelk drops. |
| Tusk Shell | — | Rare | Sea Stack Islands | Narrow, curved shell prized by collectors. Farm Sea Stack Islands with Frosted Tideclaw for best results. |
| White Abalone | — | Rare/Epic | Caldera Cay | One of the rarest findable shells. The White Abalone is a high-value target at Caldera Cay. Use your best tool and consider Eclipse timing for improved luck. |
Mutation note: any shell can receive a mutation that multiplies its sell value. The Scorched Mutation (1.7x) appears more often during Eclipse events. The rarest mutation in the game (0.01% chance) gives an 8x Shellings multiplier. Landing this on a White Abalone or a high-tier shell is the highest-earning outcome in the game.
Shell Rarity System Explained
Every shell has a rarity: Common, Uncommon, Rare, Epic, Legendary, Mythic, and Exotic. Rarity determines both how often a shell appears and its base value. Higher rarity shells require better tools (higher Luck stat) and specific island locations. The Luck stat on your tool directly affects which rarity tier of shells you can reliably find.
| Rarity | Recommended Min. Tool Luck | Example Shells | Best Island |
|---|---|---|---|
| Common | Any | Bay Scallop, Common Cockle | Bay Island |
| Uncommon | 10+ | Sand Dollar, Cowrie, Sea Glass, Clam | Bay Island / Crescent Shore |
| Rare | 40–55+ | Conch, Nautilus Shell, Mitra, Worm Snail | Sea Stack Islands / Nautilus Hollow |
| Epic | 100+ | Lightning Whelk, White Abalone, Tusk Shell | Sea Stack / Caldera Cay |
| Legendary+ | 200+ | Late-game exclusive shells | Caldera Cay / Solmere |
Conch Shells & the Hermit Crab
The Conch is one of the most important shells in Roblox Shells for reasons beyond its sell value. Your Hermit Crab companion requires a Conch to equip, and the quality of the Conch you equip directly boosts your Hermit Crab's online bonuses (luck, speed, space, and weight stats). Always equip the best Conch you have found, and upgrade to a better one whenever you find one.
The Hermit Crab also collects shells passively while you are offline. The better its stats and the better its equipped Conch, the more shells it collects. Regularly visit your inventory to claim the shells your Hermit Crab has collected — these passive earnings compound quickly and can fund several tool upgrades without any active farming.
