Bubble Gum Simulator INFINITY BGSI Pets Tier List (S–C)

This page ranks the pets that actually move accounts forward in Bubble Gum Simulator INFINITY—not every cosmetic hatch in the index. Rankings reflect level 25 stats with Shiny or Mythic called out where they change effective tier. Meta shifts after Rumble Studios Friday updates, so pair this list with Latest Updates before you trade a Secret away.

Rarity context: Secret, Celestial, and Infinity

BGSI stacks rarities from Common through Legendary into endgame bands:

• Secret — Ultra-low hatch odds (often one-in-millions on end eggs). Workhorse endgame pets like Inferno King, Crystal Overlord, and Frost Guardian live here.
• Celestial — Above standard Secret in prestige; some season tracks and bounty rewards slot Celestial units between Secret and Infinity power.
• Infinity — The current ceiling rarity. Most Infinity pets are limited event exclusives with fractional percent hatch rates. Techarium from seasonal Cyber-style eggs exemplifies the tier: unobtainable after the event unless you trade.

Higher rarity does not auto-mean higher DPS. Level investment, variant rolls, and team role matter. A leveled Epic farmer can carry mid-game until your first Secret lands.

S Tier — meta definers

These pets justify luck potions, gem banks, and serious trade offers.

Inferno King (Secret)

Inferno King sits at the top for overall progression. Its combined Bubbles, Coins, and Gems multipliers push rebirth cycles faster than almost any other obtainable Secret. At level 25 the flat stat bonus turns an already dominant pet into a rebirth engine. If you own one leveled copy, build your team around it before chasing sidegrades.

Crystal Overlord (Secret)

Crystal Overlord is the gem farming specialist. While Inferno King wins blended totals, Crystal Overlord’s gem multiplier is among the highest on any Secret—ideal when upgrades, eggs, and potions drain gems faster than coins. Pair with coin-biased teammates from Pet Teams.

Frost Guardian (Secret)

Frost Guardian offers balanced farming plus rebirth stability. Slightly less peak gem bias than Crystal Overlord but more forgiving bubble output for players who rebirth often instead of infinite AFK farming. Strong default when you only have one S-tier slot unlocked.

Galactic Bunny (Infinity, limited)

Galactic Bunny is an event Infinity pet with massive multipliers during its availability window. Limited eggs make it a trade trophy after rotation ends. Tier stays S while demand exists; long-term value tracks Events reruns and trader supply.

Techarium (Infinity, seasonal)

Techarium represents Infinity rarity done right: top-end stats tied to a narrow seasonal egg. Treat it as S+ for collectors and min-maxers when hatchable; after the event, value is almost entirely trade-driven. See Trading Values before offering limited Infinity pets.

A Tier — excellent workhorses

A-tier pets carry accounts until S-tier hatches or trades land.

• Rainbow Pegasus (Legendary) — Gem enhancement without Secret odds; great mid-late bridge.
• Toxic Demon (Secret) — Balanced farming with easier obtainability than top Secret chase targets.
• Holy Phoenix (Secret) — Power and speed hybrid for players pushing new islands post-rebirth.
• Lunar Angel (Legendary, limited) — Event grinding and coin spikes when eggs are live.
• The Overlord (Secret) — Strong practical totals at roughly one-in-fifty-million odds; trade stepping stone.

A-tier Secret pets often outperform mis-leveled S-tier placeholders. Level to 25 before demoting them.

B Tier — solid mid-game

Reliable until Secret RNG smiles:

• Golden Doge (Epic) — Early-game progression staple from common egg pools.
• Aqua Serpent (Rare) — Mid-game gem helper when Secret teams are unrealistic.
• Fire Cat (Rare) — Cheap bubble boost for first rebirth chains.
• Jellyfish (Unique) — Average farming; keep until hatch sessions upgrade slots.

C Tier — replace ASAP

Tutorial and first-hatch filler:

• Starter Bubble (Common) — Tutorial only; swap immediately.
• Basic Cat (Common) — First hatch novelty, not a farmer.
• Small Doge (Common) — Tiny bubble bump.
• Tiny Phoenix (Common) — Early gem tease without scaling.

Keep C-tier pets only while unlocking inventory upgrades. Auto-sell scripts risk deleting future fodder—manual review is safer; see Scripts ban warnings.

Variants: Shiny and Mythic

• Shiny — Roughly 1.5x stats; low hatch chance or crafting on eligible pets.
• Mythic — Roughly 1.75x on Legendary+ where supported.

A Mythic Shiny A-tier pet can bump into S-tier effective output. When trading, always state variant and level—Trading Values assumes honest labels.

Trading note

Ultra-rare pets are often faster via trade than hatch spam:

• Demand spikes after buffs listed on Updates Hub.
• Infinity pets like Galactic Bunny and Techarium command premiums after eggs close.
• Never trust “quick trade” Discord DMs; verify against Players Hub safety tips.

Hatch purists should still consult Hatch Planner so gem spend matches realistic odds.

How to use this tier list

1. Identify your bottleneck: bubbles, coins, or gems (Farming Tier List helps).
2. Level current best pet to 25 before rerolling eggs.
3. Redeem Codes before marathon hatch sessions.
4. Revisit this page after each Friday patch.

Pet power is one pillar—mechanics and island order still matter. New players should read Getting Started alongside this ranking.
