"Eep eep,"
He trusted Citro's senses, but what he wasn't sure of, was the kind of treasure that the mongoose was talking about. Treasure meant different things to different people.
For someone like him, the first thing that came to mind when he thought of treasure was the typical pirate's booty of gold, diamonds and jewels, hidden underneath a giant red 'X', in a treasure chest.
In a world like this, that kind of treasure didn't matter. And he wasn't even sure if Citro had any concept of that kind of treasure in the first place.
So to Citro, treasure could mean something entirely different. And it probably did.
But the more important thing to ask here was why exactly was Citro so interested, and what exactly could interest him to the extent of calling it a treasure?
As if reading his mind, the mongoose quickly answered.
"Eep eeeep Eeep!"
