+Create a Pokémon-style monster that transforms the object into an imaginative creature. The monster should clearly be inspired by the object's appearance but reimagined as a living monster.
 
 Guidelines:
-- Take the object's key visual elements (colors, shapes, materials) and incorporate them into a creature design
+- Take the object's key visual elements (colors, shapes, materials) incorporating all of them into a single creature design
 - Add eyes (can be glowing, mechanical, multiple, etc.) positioned where they make sense
 - Include limbs (legs, arms, wings, tentacles) that grow from or replace parts of the object
 - Add a mouth, beak, or feeding apparatus if appropriate
 - Add creature elements like tail, fins, claws, or horns where fitting
-- The object should be recognizable but creatively interpreted
