Captain Archibald Ferdinand Alexander Fitzwilliam Rupert Barnaby Manderhanes Yemen Shiny Scales the Second

From Omnictionary

"Captain Archibald Ferdinand Alexander Fitzwilliam Rupert Barnaby Manderhanes Yemen Shiny Scales the Second", or Archie, as he was known, was arguably one of Margo's dearest friends. Having acquired him only three months prior to her disappearance, Archie had provided the solice and company that she yearned for.

Characteristics

In a short poem written about Archie, Margo said this:

he Flips So Gaily, he Aplash and he Splish he's my One And Only, My archie, my Fish.

Archie reportedly had only one fin. This was surely the main reason why he swum in circles.

Archie tended to leap out of his bowl and bite the nose of any person whose face drew too near to his bowl. Those people tended not to make that mistake twice.

His Part in Margo's Disappearance

Although possibly false, Margo's attachment to this fish could hold a clue to her disappearance. Her "unconventional" style of keeping his bowl also begs some questions. Filled an inch high with foreign coins, the water a murky puce colour, and with no attempt at oxygenation, his habitat was far from clean.

Mnemonic

There has been speculation that a mnemonic of Archie's name: C.A.F.A.F.R.B.M.Y.S.S.S may hold a key to Margo's innermost feelings, however at the point of writing there have been no conclusive solutions to this problem.
