Granite crab chathead

The granite crab is a level 16 Summoning familiar. It is summoned using a Granite crab pouch.

The Granite crab has multiple uses:

  • Combat: it has a combat level of 19. In addition, its scroll Stony Shell provides a +4 boost to a player's Defence when activated.
  • Fishing: Grants an invisible +1 Fishing level boost. This boost cannot be used to catch fish that are 1 level above the player's original fishing level.
  • Forager: While the player is fishing, this familiar can forage for cod, pike, seaweed, and oysters. It can hold up to 30 of its foraged items in its own inventory. 5.5 Fishing xp is granted for each fish (cod or pike) produced by the crab.

The granite crab's Stony Shell ability



A granite crab is made by using a Summoning pouch on a Summoning obelisk with 7 spirit shards, a gold charm, an empty pouch and an iron ore in the inventory. Making the pouch earns 21.6 experience points. Using the pouch to summon a Granite crab gains 0.2 experience points, and costs 20 Summoning points. If players exchange their Granite Crab pouches with Bogrog, they will receive 5 spirit shards per pouch.

Stony shell scroll


A Stony shell scroll enables the use of the stony shell special move for a Granite crab. Using the pouch on a Summoning obelisk creates 10 scrolls and provides 0.2 experience.

Stony shell

  • The examine text "Is it a stone? Is it a crab? No! It's Granite Crab!" is a reference to a common phrase from Superman: "Is it a bird? Is it a plane? No! It's Superman!".
  • One of the things the Granite crab says is "Free fish please.", a reference to poor or low-levelled players asking for free food or money.
  • Even if you feed it Rocktails, which are supposedly made of stone, it will refuse to consume it.
