Chimpanzini Spiderini is a removed brainrot from the Roblox game Steal a Brainrot, part of the broader fan-made "Italian Brainrot" naming style that gives characters absurd faux-Italian names. Across the sources I checked, the most consistent description is visual: it is a chimpanzee-headed spider, or a chimpanzee with a spider body, sometimes noted with visible webbing or cobweb effects.
It is usually classified as Secret rarity. The character's importance is less about lore than about its unusual release history: it appears to have been a temporary renamed form of Sammyni Spyderini, then later disappeared when the name was changed back.
Community-maintained sources agree on the basic gameplay facts but disagree on some smaller details. The Steal a Brainrot Fandom page says Chimpanzini Spiderini cost $100 million and produced $325,000 per second before removal.
Its infobox on the same page currently shows $350,000 per second, which conflicts with the article text. PlayBrainrot also treats it as a Secret and says it became unobtainable after being replaced by Sammyni Spyderini.
Because of that conflict, the safest factual summary is that it was a Secret-tier unit priced at $100M, with reported income in the low-to-mid $300K per second range, most often cited as $325K/s. How players got it is also fairly consistent.
Both the Fandom page and PlayBrainrot connect it to "admin abuse" events, meaning special developer or admin-spawned moments rather than normal everyday acquisition. The Fandom page also lists stealing as another route, which fits Steal a Brainrot's core loop, where rare units can circulate after one player obtains them.
Reddit posts from players during 2025 match that picture: users mention pulling Chimpanzini Spiderini during admin abuse sessions, trading it, and later noticing that owned copies had changed into Sammyni Spyderini. Those player reports are not official documentation, but they do support the broader timeline described by the wikis.
The naming history is the most notable thing about the character. Several sources say the unit was originally Sammyni Spyderini, then renamed to Chimpanzini Spiderini, and later changed back.
The Roblox Wiki's Steal a Brainrot article includes a trivia note stating that Sammyni Spyderini used to be called Chimpanzini Spiderini. PlayBrainrot gives the clearest date anchors for the surrounding version history: it says Sammyni Spyderini was originally added on July 4, 2025, temporarily replaced by Chimpanzini Spiderini, and restored on August 23, 2025.
I could not fully verify the exact day the temporary Chimpanzini name first appeared from a primary official changelog, so that timing should be treated as community-documented rather than hard developer-confirmed. As a character, Chimpanzini Spiderini does not seem to have much independent story beyond that replacement arc.
PlayBrainrot's dedicated page is sparse and mainly says it was deleted and replaced by Sammyni Spyderini. There is no strong evidence in the sources I found of a separate personality, origin myth, or stable voice/audio identity unique to Chimpanzini Spiderini.
In practice, the character is remembered as a removed variant or transitional identity inside the game's Spiderini line, not as a fully separate lore-heavy figure. That matters if you are cataloging it: describing it as a short-lived game state is more accurate than presenting it as a long-established standalone mascot.
Some details remain uncertain. Source attribution is inconsistent: PlayBrainrot names "Sammy (Deleted)," while the Fandom page credits "BRAZILIAN SPYDER." Explanations for why the rename happened are also speculative.
One community wiki suggests a possible reference issue, but it labels that reasoning as an assumption rather than a confirmed fact, so it should not be treated as established lore. What can be said with confidence is narrower: Chimpanzini Spiderini was a Secret brainrot in Steal a Brainrot, visually a chimp-spider hybrid, associated with admin abuse availability, later removed, and ultimately folded back into Sammyni Spyderini.
If uncertainty matters, the safest interpretation is that Chimpanzini Spiderini was a temporary, now-unobtainable name or state in the history of Sammyni Spyderini rather than a fully separate long-term character.
