Rainforest is a delightfully atmospheric module. I imagine this would be a nice one to leave on in the background while reading. In fact, I might go do that after I post this.

I have no idea what Triazzle is. I'm sure it's very pretty though.

This module has a "Creatures" button that allows you to toggle which creatures you want to display. It's a bit like a lot of the aquarium modules (which I didn't even talk about in this series. What an oversight on my part!) The creatures in this module are dragonflies, Peruvian frogs, Lehman's frogs, click beetles, blue butterflies, and turtles. Not really any good reason to not have them all on, unless you really don't like bugs, I suppose.

The "Number" slider determines how many critters will show up on the screen at once. The "Background" dropdown menu lets you choose a background on which your critters can play. Options include things like leaves, moss, and rocks. Though you can use your desktop or just a blank background if you desire. And, of course, there's a random option which, as I often do, encourage you to select. The background has no effect on the greenery and flowers that show up on the edges of the screen, though you can toggle that off completely by de-selecting the "Foliage" checkbox.

I'm not sure much else needs to be said about this one. Just leave it on a loop, relax, and enjoy the birdsong and jungle noises while pretty creatures scurry about.
