They came upon a ""car-crash"" trap set by Lex Luthor - it was a faked injury to driver Eve (his accomplice in a slinky and revealing dress) lying on the payment from an overturned drone car accident.His mount was killed and he was then dragged across the ice.The hidden Rebel base was located in a large ice cave, where Han Solo had just returned from his own scouting expedition.Although Shrek was extremely reluctant ("Somehow I don""t think I""ll be welcome at the country club"), calling it a "bad idea," Fiona eventually convinced him to participate (with Donkey also accompanying them, singing the theme from the TV showRawhideas they departed)."At the same moment, a doddering, tardy Mr.Charles Chipping (nicknamed "Mr.Chips") (Robert Donat), the retired master who still lives on the school grounds, ignores his doctor""s orders and is glimpsed shambling along in full academic garb (with mortar board and walking stick) toward the assembly.
