Tiki's the same as Poppy, I think he practices on his own for a while before randomly coming out with new stuff and often a new word each day for a few days, then nothing for a while, just because we dont here them dosn't mean they are not listening and taking things in. Some of the stuff Tiki says I didn't even teach him, where as the stuff I do he does not always say.

But once he has perfected his words he is mostly activly talking at sundown time for some reason, rattling of all the words he knows (including new words I didn't know he knew.)
