Cap'n Izzy No-Beard is an non-player character who can be found at the entrance of the Brimhaven Agility Arena minigame. He has a pet parrot which he says has "cracked Jenny's tea cup." He and his parrot guard the entrance to the Agility arena, with a fee of 200 coins to use the arena. The fee is halved with Karamja gloves 3 equipped.
Captain Izzy is also a master of Agility, and with level 99 Agility players may purchase an Agility cape from him for 99,000 coins. As with all skillcapes, it also comes with the matching skillcape hood.
Cap'n Izzy is the destination for a hard clue scroll with the anagram "O BIRDZ A ZANY EN PC". The parrot will give you a challenge scroll, asking how many banana trees are in the Banana plantation, the answer to which is 33.
