Mr. Bean is all set to have a delightful time at the fair in Southsea, but after a baby's pram gets caught on his mini, his day inadvertently turns into fun fair with baby. Despite his new sidekick, Mr. Bean is determined to enjoy each and every ride including the bumper cars. When this plan doesn't work out so well, Bean decides to leave the child in a kiddie ride while he rides the roller coaster and tries his luck as well as some dirty tricks at the arcade. When he returns, the ripe smell coming from baby indicates it's time for a happy change. Finally, in an effort to stop the baby from crying, Mr. Bean buys a bouquet of balloons to tie to the stroller, but he may have bought a few too many! Bean thinks all's well that ends well when the airborne pram touches down beside the baby's mother but he finds that in the meantime he's collected a stray dog.
