Actually, yeah....I do know a few words in Stitch's language.
Soka = Sorry
Okie-taka = Okey-dokey
Gaba = What
Achi-baba = Friend
Iky = Yuck
Meega nala quista/kweesta = (Some sort of naughty or threatening phrase.)
There is so much more.....
I agree that there should be more L&STS posts. There are two episodes left before season 1 ends, I believe...'Bad Stitch' and another one, which will air Monday, Feb. 9 (no episode title shown, though...just the description).
