Collect All Pets!

Collect All Pets! is a pet collection and fusion simulator on Roblox developed by TwoZoos where players hatch eggs, discover over 240 unique pets across an 8-tier rarity ladder, and fuse duplicates to climb toward Mythical - the highest rarity in the game. Launched in February 2022, it has surpassed 200 million visits and consistently draws 3K-12K concurrent players, placing it firmly among the top pet simulators on the platform.

The core loop begins simply: walk over Gold drops in your current zone to collect them, spend Gold at the zone egg station to hatch pets, and build your collection across the 8-tier rarity ladder from Common to Mythical. The Fusion mechanic is where progression deepens - two pets of the same rarity combine into one pet of the next rarity up, so two Epics become a Legendary, two Legendaries become a Prodigious, and so on. Reaching Mythical requires multiple full fusion cycles and is the game's primary endgame challenge:

• 💰 Gold - the primary currency collected by walking over drops in your zone; used to hatch eggs at the zone egg station
• 🏠 Zone Progression - each new zone has its own egg pool with higher base rarities, unlocked by spending Gold on upgrades
• 💎 Fusion - combining two same-rarity pets into one of the next rarity; the only path to Prodigious, Celestial, and Mythical
• 💎 Shiny Pets - rare variants with roughly a 1-in-1,000 hatch rate that deal 80% more damage and appear visually distinct
• 💎 Metallic System - a separate 5-tier variant system from Chrome through Titanium, governed by the Metallic Luck stat
• 💎 Giant Pets - oversized versions of any pet; a Shiny Giant combines both modifiers and is extraordinarily rare

All 240 pets in the Pet Index can appear in Shiny, Metallic, and Giant variants, and completing the full index across all variants is the game's ultimate completionist challenge. Quests provide structured daily and weekly goals alongside the main collection loop.

TwoZoos publishes multiple codes per update cycle, making Collect All Pets one of the most code-active pet simulators on Roblox. For a comparable experience built around a different economic model, see Pet Simulator X.
