Mars and his wife, Mia, are out on their species version of a second honeymoon, and Hector has to keep an eye on the triplets while the parents are away, but Marsu-Sitting is a harder job then babysitting a human child for several reasons: one, the species have great appetites and high metabolism (they have to be feed 7 meals a day!), two, they have to be kept loved and amused (Bibu proved the hardest with this one, as he kept crying), three, the matter of cleanliness (the triplets hate bathtime and run off when they just need to have berry juice wiped from their faces), but the last, and most important rule the job requires, they have to be protected from dangers, like jaguars... or worse, Backalive! After this, Hector will need a vacation!
