The greenhouse frog (Eleutherodactylus planirostris) has been found in Guam, according to this story from the Honolulu Advertiser. Why is a Hawaiian newspaper reporting about Guam? The greenhouse frog is a great source of food for the dreaded brown tree snake (Boiga irregularis), which Hawaiian officials are desperate to keep out of their state. More food means more snakes, making the chances of an accidental introduction even greater. Unfortunately, the greenhouse frogs are quiet, and a lot harder to track down than the other frog species making its way around island ecosystems, the coqui (E. coqui).
