Captain Tighty Whitey first appeared in the episode On the Air and Out to Sea. He held Grojband captive and made them walk the plank because of them messing up his radio station. Corey convinced him that he and his band were pirates too and became part of his crew only to figure out that he and his his team constantly plunder stuff. Corey tries telling them to stop which ends up with him getting planked with his bandmates. Corey saves them by singing a sea shanti and getting them to like them. Grojband left the team after that and Captain Tighty Whitey spent his time listening to their songs. He appeared again, in a cameo the episode Rockersize. He was seen dancing with Shaven Beard and Barnacle Tim, listening to the radio and an old lady came up and smashed their ship causing it to sink ad blow up because the music was too loud. He appeared again in the episode The Pirate Lounge for Me where he and his crew decided to plunder the garage because he thought there was treasure there. He forced everyone else to start digging holes all over the yard to look for the treasure. In the end of the episode, they actually found a treasure and they left. He made a cameo in the episode, "It's in the Card", being one of the people who received a Valentines card from Grojband that made him turn against Shaven Beard and Barncle Tim and made them walk the plank. In the end of the episode, they got back together again because of Corey's song. In the episode Curse of the Metrognome, he went to the clock store and asked what time it was, but before he could finish. The shop owner told him it was time to get a new watch. He made his final appearance in the episode, "Hear Us Rock Part 1", where he, Shaven Beard, and Barnacle Tim were all rampaging about, plundering and stealing everything because it was the apocalypse.
