[Scripting Question] how can i duplicate the bike or make a similar item in Essentials 20.1?

[Mushipkm]

i tried duplicating the bike bc i want to make rideable pokemon

but so far i just made the item usable
it plays de bicycle bgm

but idk how to display a different graphic for that item

tried editing metadata.txt and the game_player data

but i can't figure out how to display the graphics bc the metadata debug doesn't seem to recognize the charset

if you know how to duplicate the bike or how to make a new one similar to it
it would be really helpful
thanks in advance hope someone can help :D
