Marsh minnow

Marsh minnows were Sil's favourite snack, a kind of newt mostly eaten live. (PROSE: Mindwarp) Indeed Kiv once berated his subordinate for always eating them, and slightly insulted his junior by suggesting that Sil might well measure profit in whether it would be sufficient to "keep [Sil] in marsh minnows". (TV: Mindwarp) The Sixth Doctor ate one and found it roughly as pleasant as eating an internal combustion engine. (PROSE: Mindwarp)
