The Slap Battles Wiki reports a 1 in 7,500 chance per Replica ability use for bob to spawn—about 0.0133% per use. That is a community-maintained figure, not an official probability published on Roblox. Spawning bob and earning the badge are separate: bob must also have someone to target in the arena.
What does the 1-in-7,500 chance mean?
The reported odds apply to each use of Replica’s ability. The Slap Battles Wiki records the chance as 1/7,500, or approximately 0.0133% per use. The official Roblox Slap Battles experience page describes the game but does not publish bob’s odds, so treat the number as a community-reported mechanic rather than an official probability disclosure.
A 1-in-7,500 chance is not a countdown: it does not mean bob will appear by the 7,500th use. The cited source does not establish a guaranteed attempt count or wait time. Calculating an overall chance across multiple uses would require assumptions about independent rolls and unchanged game mechanics that are not confirmed here.
How do you get bob’s badge?
- Equip Replica and use its ability to try for a bob spawn.
- Make sure another player is present in the arena when bob appears. According to the Slap Battles Wiki’s bob page, bob needs someone to target for the badge to be awarded.
- Wait for the badge award if the requirement is met. The wiki says the method works in private servers and recommends having a friend or alternate account active in the main arena. That helps provide a target; it is not reported to increase the spawn odds.
Does the chance go up after each Replica use?
No increasing chance or pity system is supported by the cited page. The wiki specifically rejects the claim that the odds rise after every use, so do not assume unsuccessful attempts make the next roll more likely.

How reliable and current are these odds?
The wiki’s change history records a shift from 1/1,000 to 1/7,500 and later fixes, including a badge-award fix in June 2025. Its page history reaches March 2026, but the figure is still community-maintained, not independently confirmed by an official developer statement in the available sources. If exact live mechanics matter, check the game or current community documentation.
Avoid exploit scripts or hacking to try to force the spawn. Roblox’s experience description warns that exploiting or hacking results in a permanent ban.
