Creatures Caves

I'll just... list off a bunch of things, I guess? Most of these are in-game tools, since there aren't a lot of hud mods. There is the Creature nametags. It displays the name of every creature under it, and you can even give them a custom tag. There is also a custom menu for the DS egg layer. It adds an actual breed selection menu to Muco, and is one of the most useful add ons ever. Oh, and there is a Creature Counter that displays how many creatures/eggs are in the world.

As for in-game tools, I use the Garden Box in almost every world. It let's you place plants, animals, and decorations everywhere. There's even an option for seasonal food sources, which makes things like seasonal wolfling runs much easier. It's also has one of the few edible bug agents I've found, that isn't a part of a metaroom anyway. I love carnivorous Norns, so I end up using the glow worms and snails a lot. Plus Creatures love pushing or hitting the little worms.

The X-ray and Eggernator usually end up in my worlds. The x-ray is one of the most useful things, since it can graph any chemical and shows how healthy a Norn's organs are. The graphing isn't quite as detailed as the biochemistry set, but it's good for most things. The eggernator lets you mess around with eggs, like insert up to ten eggs into one Norn (even males.) It also let's you extract eggs from dead Norns. I usually use it to freeze or move large groups around though. It also has a tendency to not update immediately after you pile enough Norns in there, but it takes like 20+ Norns to do that. There was an eggernator 2, but I don't think it worked properly.

The Wolfling monitor and Eggonicer are both pretty good for wolfling runs. The wolfling monitor can track chemicals and even export Norns based on those chemicals. The Eggonicer helps manage eggs, but it slightly glitchy. Neither of them are newbie friendly, especially the wolfling monitor. The Population Control Panel is what I end up using a lot of the time. It's user friendly, works like it should, and I can set it up and forget it.

As for Caosy things... The only caos commands I use a lot are some .cos files I've made and the "kill hots" command. One cos file injects Primordia's critters and bugs into the Meso because the Lepts are utterly adorable and I need them in every world. The other two I use just change parts of metarooms, like removing dangerous weeds, or adding smell/ca emitters to certain rooms. Also the magic words agents are sort of like user friendly caos commands. The room edits, cloning, and mark agents are the ones I use the most. Slightly related to that is Devthing. Devthing does a lot of stuff like count eggs or Norns, give everyone vocabulary, and has things like a caos command menu and chemical graph/injector. It can also kill all of the Creatures in a world... I pressed that last one on accident once and still regret it.
