"The Cheburashka is a jig head consisting of a detachable metal hook and a round weight. Put the hook in the metal hook and push the hook into the hole in the weight so that the round main parts of the hook are visible. Now the hook locks in place. Attach a fishing line or jig to the hook and you're done. The jig attached to the Cheburashka moves freely from the eye of the hook - unlike the ""norm"" jig head, which is permanently attached to the weight, thus stiffening the jig's movement. Cheburashka allows the jig to move irregularly and very naturally. Works well with standard hooks, offsets and treble hooks. Also recommended to use Mikado's Sensual double hook."
