For players venturing deeper into the wonderfully chaotic world of Steal a Brainrot, acquiring some of the more elusive companions can be both a badge of honor and a tactical advantage. One of the more bizarre yet sought-after additions to your roster is the mischievous and creepy duo: Chimpanzini Spiderini. If you’ve been wondering how to get Chimpanzini Spiderini in Steal a Brainrot, this guide will walk you through what it takes — and why it’s worth the trouble.

Who Are Chimpanzini and Spiderini?

Before diving into how to acquire them, it's important to understand what they bring to the table. Chimpanzini Spiderini is a fusion-style companion — part simian trickster, part venomous crawler — known for their dual-phase combat mechanics. They offer agility-based buffs, chaos damage over time, and unique debuffs that disrupt enemy formations.

In other words, if you’re building a team focused on disruption and mobility, they’re a perfect fit.

How to Start the Unlock Questline

To start your journey toward unlocking Chimpanzini Spiderini, you must first complete the side mission “Banana Bait & Eight-Legged Fate”, which becomes available after reaching Brainrot Level 17. The quest NPC, Curio the Cracked Zoologist, can be found lurking near the abandoned circus ruins in Grimbletown’s Forgotten Fairgrounds — an area often overlooked by newer players.

Once you engage with Curio, you’ll be given a multi-stage quest involving:

• Banana luring traps (requires crafting via Tinkered Fruit Parts)

• A stealth mission in the Spider Carnival Caverns

• A short but brutal boss fight against The Clownarachnid

The Key Challenge: Dual-Bond Trial

Once you’ve completed the fetch quests and passed the cavern trial, you’ll be thrust into the Dual-Bond Trial, a combat challenge where you must defeat waves of hybrid creatures while keeping two NPCs alive. This section demands precise timing, companion coordination, and smart use of AoE control.

Tips for passing the trial:

• Bring companions that can taunt or stun large groups.

• Equip mobility boosters to dodge ranged webs and surprise leaps.

• Consider using the Sticky Pudding Bomb—an item that’s oddly effective against spider-types.

Only upon completing this trial will you receive the Primal Bond Totem, which you must place at the Sacred Tree of Tangletuft during the Brainrot moon phase. Do it right, and you’ll trigger the encounter to recruit Chimpanzini Spiderini.

Why Chimpanzini Spiderini Are Worth the Trouble

Beyond the bragging rights, Chimpanzini Spiderini offer mechanical advantages you won’t find with many other companions. Their passive ability, Trickspin Webplay, gives you a 12% chance to confuse enemies for 3 seconds on critical hits. That’s a game-changer in PvP and raid scenarios where crowd disruption is key.

They also scale well with “Madcap” builds — making them ideal for players who like chaos magic, speed, and unpredictable battlefield effects.

Getting Chimpanzini Spiderini isn’t just about ticking off a checklist — it’s about proving you’ve mastered a strange corner of Steal a Brainrot's chaotic ecosystem. From stealth missions to mind-bending boss fights, the road is full of surprises. But for those determined enough to follow through, the reward is one of the most unique and mechanically rich companions in the game.
