Hi,
While I really like this character, there are several grammar and spelling issues in the speech file and they kind of bugged me. So I fixed most of them in my local copy, and I just wanted to share my changes with you.
Here's the updated speech_cleo.lua, feel free to throw them back into the mod (if you want to): http://pastebin.com/rfWkRPD4

Full list of strings I changed:
hound mound, berries, berry bush, pine cone, twigs, red gem, purple gem, chester, lightning rod, campfire (medium), ashes, burning evergreen, large jerky, corn, penguin, tentacle spots, spider gland, hunger announcement, battlecry, nightmare timepiece, nightmare rook, double cave flower, slurtle home, spider hider, sleep blowdart, bone shards, butter, cooked cactus, cooked carrot, cooked meat, endothermic fire, catcoon den, chess junk, frog, flower, hambat, hammer, hound, voltgoat, voltgoat horn, spear, tentacle garden, slippery announcement, wormhole (open), accomplished announcement

Cheers!
