Highly detailed vintage retro vinyl sticker illustration of a chaotic rat standing upright on hind legs, clutching an oversized pizza slice with melting cheese strings, devious gleaming eyes, sharp teeth showing in a wide unhinged grin, fur slightly messy and disheveled. Intricate fur rendering with fine parallel hatching, dense cross-hatching for shadows on belly, detailed pizza texture with pepperoni and cheese hatching, long segmented scaly tail curling dramatically behind, tiny claws on paws, prominent rounded ears with inner ear detail. Small grease drips from the pizza slice. Bold curved arched text "GOBLIN MODE" above the rat following a half-circle path and "ACTIVATED" curving below in matching half-circle, in bold condensed slab serif font. White background, professional black ink illustration, vintage engraving aesthetic, no border, no frame, isolated illustration centered composition.
