It is nothing but a scale from the red gyarados. It has not one special ability or thing about it. ( just reminds you of the time you caught the red gyarados )
after you beat or catch the red gyarados he will drop a red scale
The Red Scale is a scale that you obtain after defeating/capturing the Red Gyrados in the Lake of Rage in Mahogany Town.
You give the red scale to Mr.Pokemon and he will give you an Exp.Share.
pH scale for red litmus is from 8 to 14
It's a Red Scale and after you catch the Red Gyrados a message pops up saying you have found the Red Svale.
In the Lake of Rage above Mahogany Town, there is a red Gyrados. Either catch it or make it faint to find a Red Scale. Give the Red Scale to Mr. Pokémon to get the Exp. Share.
After the fight with the red gyrados you get a red scale. Take the red scale to Professor Elms house on route 30 or 31. He will then want to trade that scale for a exp. share.
I believe you have to look for Red Gyarados for a Red Scale.
in johto, go to lake of rage and in the lake is a gyarados [it's red] defeat or capture it and ya'll receive the red scale.
You need to catch the red Gyarados which is holding the red scale otherwise your screwed. You need to either catch the red gyrados or make it faint. Answer by sasukelovr
You have to catch or defeat the red GYARADOS
After fighting the red Gyarados at the Lake of Rage, you will get a Red Scale. You need to take this scale to Mr Pokemon on Route 30 (North of Cherrygrove City). He will trade the Experience Share item for your Red Scale.
