About Los Spyderinis
Los Spyderinis is a Brainrot released on August 23rd, 2025. This brainrot can only be obtained from the Sammyni Ritual. You can do the Sammyni Ritual by making a square with four Sammyni Spyderinis. This ritual also triggers the Sammyni Invasion event. It was formerly obtainable from the Admin Lucky Block and from Sammy's Base. But it was removed from the Admin Lucky Block due to lack of space.
Los Spyderinis is a secret-tier brainrot in Steal a Brainrot, the Roblox collection-and-trading game where every pet generates passive income and can be upgraded with mutations and traits. At base, Los Spyderinis earns $425.0K/s and costs $125.0M from the in-game shop — those numbers are the floor, before any multiplier from mutations or trait stacking is applied.
Across live Eldorado marketplace listings, Los Spyderinis prices currently range from 50 Robux for the Default variant up to 733 Robux for Cyber — a 14.7x spread reflecting the multiplier gap between mutation tiers. Mutation multipliers compound on the base income, so the same Los Spyderinis body at a higher-tier mutation out-earns its Default variant by exactly that ratio per second.
