Captain Haddock's horse is an equine, perhaps a brown Stallion, that appears in The Seven Crystal Balls.
History[]
The horse is first seen when Tintin arrives at Marlinspike Hall in The Seven Crystal Balls to pay a visit to Haddock, who at the time was trying to adjust to a more sophisicated civilian lifestyle. It is shown that although Haddock has been becoming accustomed to horseback riding, it is made clear he is still an amateur at it as Tintin and Snowy first spot his horse returning back to the estate without him, followed by the disadvantaged seaman arriving after most likely losing his balance, resulting from falling off his horse.
The horse does not appear in any further events or later installments of the series.
