Prize Mice

The Hunter must be Recruit or higher and have finished the tutorial.
The Hunter needs to encounter a regular mouse (Catch or Failure to Catch) to have a chance of a prize mouse encounter.
During a giveaway the chance to encounter a prize mouse is ~15%.
Outside of a giveaway the chance to encounter a prize mouse is ~0.067%.

The Treasurer, Snooty and High Roller are always added to the prize mouse population.
The Mobster and Leprechaun are added to the population if they are not on their cooldown period.
The cooldown period is a global setting, so once a Mobster or Leprechaun are caught by a hunter, no other hunter in the game can encounter one until the cooldown period has passed.If a hunter attracts and misses a Mobster or Leprechaun, that mouse is still available and the cooldown does not apply.
During a giveaway, the cooldown period is 1-3 minutes.
Outside of a giveaway, the cooldown is 1-17 hours.
The Treasurer is most common, through to the Leprechaun which is least common.

Note: the encounter rates and cooldown times are from the FeedBack Friday on 24 July 2020, there were different encounter rates and cooldown times in the past.

Note: Prize mice and other "bonus" encounters work slightly differently than a normal encounter to avoid these mice interfering with normal area progression. For example: Bonus encounters do not propel your submarine in the Sunken City, break streaks in the Warpath, affect positioning in the Valour Rift Gauntlet Tower, etc. Prize mice and bonus encounters being exempt from area-specific gameplay also causes them to be exempt from area-specific or other "special" trap bonuses and effects. As a rule of thumb, any trap bonus you see under "special" in the Camp page trap selector will not apply during a bonus encounter with a prize mouse.
