One of the Pets in the game, Cool Rock

Pets are unlockables which give permanent bonuses.

Pets are not items and will not appear in the bank. Instead, all acquired pets can be seen within the Pets section of the Completion Log, and will also appear in the skilling minibar if acquired from a specific non-combat skill.

Once a pet is acquired its effect is permanently active and cannot be turned off.

Acquiring Pets

Skill Pets

There is a pet for each of the skills in the game. The Chance to acquire a Pet on any given action of a Skill is:

[math]\displaystyle{ \dfrac{\text{Time required for action (seconds)} \times \left ( \text{Virtual level of Skill} + 1 \right )}{25\;000\;000} }[/math]

For example, a player with level 99 Crafting who has unlocked Perpetual Haste and is wearing the Crafting Skillcape will take 1.9 seconds to complete an action, which means each action will give a [math]\displaystyle{ \tfrac{1.9 \times (99 + 1)}{25,000,000} = 0.0000076= 0.00076\text{%} }[/math] chance to earn Caaarrrlll.

For combat an action is an attack. For Slayer, an action is an attack against the player's current Slayer task. For special attacks or spells which perform consecutive hits, the action time for any hits after the first is the duration between the current hit and the previous hit, not the attack speed displayed within the Combat UI.

Larry, the Lonely Lizard works slightly differently: Larry is rolled when crops are harvested. The chance formula used is unique to Larry, as explained here.

It is possible to acquire a Pet Offline.

Boss Pets

Each time the player completes a dungeon, they have a chance to receive the Boss Pet for that dungeon. The chance to receive the pet depends on the dungeon:

• For the lower level dungeons ( Chicken Coop up to Dragons Den) the chance to receive a pet is 1-in-350.
• For Volcanic Cave and Infernal Stronghold the chance to receive a pet is 1-in-200
• For the God Dungeons, the chance to receive a pet is 1-in-150
• For Into the Mist and Impending Darkness Event, the chance of receiving the pets are not random. Instead, the player is guaranteed to unlock the Into the Mist pet after completing the dungeon five times, while the Impending Darkness Event pet is guaranteed after a single completion.

Other Pets

There are a few pets that don't fall into the other categories:

• The Golden Golbin is a guaranteed drop after reaching a total Golbin Kill Count of 42,069. Both melee Golbins in the Golbin Village and all golbins in the Golbin Raid count.
• Ty is rolled whenever any action is taken that rewards Mastery xp, the chance to acquire is the same as for skill pets.
• Mark is obtained when the player reaches the maximum mark level of 4 in each of the Summoning marks.
• Peri is rolled with a 1-in-7,500 chance for each monster killed in Perilous Peaks.
• Otto is rolled with a 1-in-7,500 chance for each monster killed in Dark Waters.
• Ripper the Reindeer was available as part of the 2020 Christmas Event and is not currently available. Ripper is not required to reach 100% Pet Completion
• Jerry the Giraffe and Preston the Platypus can be purchased from the Golbin Raid shop. Neither is required to reach 100% Pet Completion
