Basil was a parrot that O.B. found in a cage by a bus stop in August 2005. O.B. ended up taking Basil back to 3 Oakdale Drive, Flat 3 to the joy of Tom Cunningham, until a foul-mouthed Basil proceeded to swear at Tom. O.B. was left conflicted as Tom's brother Max demanded that he gave away the bird, so O.B. temporarily kept him at The Dog in the Pond. The pub customers took a liking to Basil, until he began making inappropriate comments.
After Basil told Jeremy Peterson to "watch [his] pint" before dropping a glass, O.B. began believing that Basil was psychic and Steph Dean attempted to capitialise on this by making Basil a fortune teller. Basil ended up driving away customers so O.B. had Craig Dean deal with him. Craig ended up selling Basil to Frank Finnigan, an entertainer for hen nights and stag dos.
