you can not :(
There isn't an item called a Cozy Ball in Pokemon Ruby. There is however a Poke Ball called the Luxury Ball. You can find a Luxury Ball in the Abandoned Ship. Luxury Ball is also a reward for winning the master rank contest in Lilycove City after first winning the Ribbon.
You need to have a Pokemon with move SURF and DIVE to do this... First SURF to Route 108 (between Dewford Town and Slateport City) 'til you find an Abandoned Ship and enter it... Next go to the cabin inside the ship where there is a deep part of water, use DIVE and move underwater 'til you find a shiny part in there then move up... There you will see six cabins... One of the cabins has Luxury Ball...
Surf east from Dewford town. You will find an abandoned ship. There will be some people on it. Check in every room. In one of the rooms there will be a puddle of water. Use dive and you will find a luxury ball underwater. Go allitle further in a room and come up. You will find a scanner which you can exchange for a deep sea scale or deepsea tooth. You can get more luxury ball by beat the master rank in contest.......repeat and repeat make sure you are the win in the contestlol
Luxury balls are a type of Poke ball for the game Pokemon. They are hard to find, so are worth more than other types of balls.
in the abandon ship and is awarded to you if win a Master Rank Contest for the second time.
You find it in the abandoned ship.
abandoned ship
you find it in that abandoned house thingy
you can find them in the abandoned power station. As well it is you starter Pokemon.
You find it in the casino for 4000$ or in the abandoned ship
On the abandoned ship.
i think if you catch a Pokemon with a luxury ball wich you find in the abandoned ship and leave it with the day care man in a couple days it evolves. not to its next form but its shiny form yeah that's not true the way to get a shiny Pokemon is to get lucky ....very lucky the odds to get a shiny are 1 in 8,192 good luck. never mind that is not true you have to get cheats to catch shiny Pokemon
