On the eleventh day of Christmas my dear Kerbal gave to me: 11 Terrier engines, 10 Toroidal aerospikes! Three by three snooker balls numbered from 9 down to 1, 8 Lander's landing, 7 sentinels-a-scanning, six pieces of debris, Fiiiive Maaammoth Enginesss! Four static boosters, three models of Kerbin, two NERVA engines and one snack box that they made empty.
