Night at the Zoo: LatecomersExpansion

From BoardGameGeek:

The Zoo has opened four new enclosures, welcoming more animals into the park. Under the cover of darkness, these curious beings joined their friends and escaped! Help them return to the Zoo safely, but be careful – some of those new arrivals have more complicated ways of moving! This expansion doesn't alter any of the base game rules; it adds four new animals to choose from. -description from the publisher
