Ale

Greenbean shows the ale and ambrosa he swiped for Apollo's party (Lost Planet of the Gods, Part I).

Ale is an alcoholic beverage. Greenbean pilfers a quantity of it (as well as some ambrosa) from the Officer's Mess for Apollo's sendoff party (before Apollo's marriage to Serina). Security notices its absence and investigates the party, but is ultimately sent away by Colonel Tigh, who covers for them (Lost Planet of the Gods, Part I).
