Set at the exact same time as "Ringing In The New Year". Spoiled Rich recruits a dozen criminal ponies (who DO NOT include ANY of the major villains in this series; these ARE just talented, but relatively normal crooks) to help her rob six of the biggest casinos in Los Pegasus on New Year's Day after her husband cuts off her allowance. However, Lyra, Bon Bon, Flash Sentry and Sunset Shimmer are ALSO heading for a couple of the casinos as part of a holiday trip. Can the four vacationing heroes foil the planned heist?
You misspelled "Las Pegasus".
