Which accessories fit which flashlight
Every RGB Critter accessory fits every RGB Critter.
All three RGB Critter generations share the same front threads, so whips, sabers, blades, tubes, dusters and costume bundles twist onto any RGB Critter ever made. The few exceptions are listed below.

Compatibility FAQ
Do my old accessories fit the new RGB Critter BT?
If they were made for any RGB Critter (1.0, 2.0 or BT), yes: all three generations share the same thread. If they were made for our first generation color changing flashlight, discontinued in 2018 before the RGB Critter line, no. That older flashlight used a different thread size and is not cross-compatible in either direction.
What is the difference between the RGB Critter BT and the 2.0?
The BT (current model) adds Bluetooth app control, USB-C charging and a three-button interface. The 2.0 and 1.0 are discontinued, charge over Micro-USB and have no app. Reading a review of the 2.0? It describes the older model.
Can I use the RGB Critter with Light Painting Brushes (LPB) tools?
Yes, with the Critter to LPB Adapter, which threads the Critter into any LPB-compatible tool.
How do I connect two Critters together?
The Critter Connector joins two Critters back to back for staffs and double whips. The Inverse Critter Connector feeds two Critters into a single saber for double brightness.
One Light. 200+ Creative Tools.
The programmable light source that twists into whips, sabers, staffs and light painting tools.
