Twisted Ribecca

Ribecca is a Halloween-only Common, and the wiki lists nothing beyond the baseline for her: walk 10, chase 18 (tied for 15th of 37, the median), vision of 26 in a circle and 60 direct, hearing out to 125 and an attention span of 1.5 seconds. With no mechanic and no unusual stat, the risk she adds to a floor is the same as any other Common, which is limited and avoidable by anyone who watches their Stamina.

Where she differs is in who she belongs to. Her own Toon is a flat 3 stars in every stat, and its passive makes it immune to all applied debuffs except those from trinkets. That matters because most Twisteds on this list work through status effects such as Slow, Tired or Confused, and a Toon that ignores them can shrug off Bassie's flowers or Rodger's fake capsule. Against Ribecca herself the usual rule holds: break line of sight and wait out the 1.5 seconds.

She entered with the 2025 Halloween event and is listed as returning for 2026, so she can appear while the event runs. At 100% Research you receive the Bone Needle and Thread trinket, which highlights Pumpkins and Halloween decor around you every 10 seconds.
