Style: dark cartoon horror toy mascot with bold black outlines, flat cel shading, grimy scuffs, and a muted palette of dirty pink, bone white, blood red and bruise purple, with line weight matching the attached base exactly. The bear is three-quarter-right with its head tilted and shoulders hunched.

Grip: the item is held in the base's raised left paw (viewer's left), centred at (225,650). Redraw that paw's pink fuzzy fingers and cream claws exactly in the base's colours, closed in a clear fist around the item's handle. Each finger must be separately readable, with claw tips visible over the handle. Never let the paw become a black blob. The handle passes through the fist roughly vertically, tilted a little up and outward to the upper-left.

Placement: the working end (head, blade or bar) rises above the paw within x 40-420, y 120-600. It must never cross the face, muzzle or eyes (x 350-680, y 280-600). The handle end below the fist stops by y 730. The forearm (x 120-290, y 700-900) and the belly stay fully visible: draw nothing over them.

Items (2 variants each, each pair clearly different in colour, wear and blood amount):

01-02: baseball bat wrapped in barbed wire with blood spatter (raw wood; dark varnished wood).

03-04: bent golf club with blood (steel iron head; black driver head), with the bend in the shaft and the grip tape in the fist.

05-06: small chainsaw, rear handle in the fist, bar and chain pointing up to the upper-left (rusty orange body; grimy yellow body). The body sits above the fist and does not hide the forearm.

07-08: rusty meat cleaver, wooden handle in the fist, blade above (pitted rust; bloody chipped steel).

09-10: bloody hockey stick, shaft in the fist, the blade end up and out to the upper-left (taped wood; cracked black composite).

11-12: crowbar, straight end in the fist, hooked claw end up (rusty red-painted; bare black iron with blood).

Materials come from the items themselves (wood, steel, rust, tape, wire, plastic), never pink plush. Draw only the item and the gripping paw; draw nothing that sits behind the bear.
