Amazing...  great job.. so COMPLICATED

@humble_roots

1:35 - Stamp a puppet into the scene.
2:42 - Open that puppet's logic chip (scope in required).
3:55 - Search the dreamiverse for the "Sneak Chip" and stamp it into the puppet's logic.
6:17 - Connect the value outputs for your "walk speed" and "run speed" variables inside the Sneak Chip to the corresponding value inputs for the puppet's tweak menu (L1+Square).
9:42 - Open the puppet's main controller sensor and connect the desired button's output port to the Sneak Chip's input port: "Activate Button".
12:52 - Animate the "crouch pose" keyframe in the Sneak Chip (L1 + X). Pose the puppet.
24:12 - Animate the "crouch pose" keyframe again to reduce the controller sensor camera tab's "camera height" and "camera distance" parameters to your preferred view of the puppet whilst sneaking. 
26:40 - Add a ~2 second power up/down to the "crouch pose" keyframe via its tweak menu (L1 + Square) to eliminate the transition choppiness.
28:50 - Delete or hide the 2 pink help text displayers in the sneak chip.

40 minutes to get some sneaking going. Dreams in a nutshell.
