Wooper's Cobblemon

Based on the official cobblemon modpack, but with some changes to make wooper extra friendly and adventurous.

friendly features

These include You're in Grave Danger and Forgiving Void to avoid stress, along with a Cobblepedia accessible from the inventory screen to walk you through cobblemon (via PatchouliButton).

If you're ever not sure what block you're looking at, you can press 'x' to toggle Jade's info box which describes whatever you're looking at and tells you if you can mine it with your current tool. Other small quality of life changes include a button to sort inventories automatically, craftable backpacks for more inventory space (hover over your chest slot to see the special backpack slot, and press 'i' to open it outside of your inventory), and lots of little tweaks you hopefully won't even notice smoothing out things you would've noticed.

adventurous features

There's other mods that add new things as well as cobblemon, but it's all tucked away so the game should still feel like vanilla + cobblemon unless you want to dive in. If you do, the guidebook button in the inventory also provides access to guidebooks for Ad Astra and Mythic Charms. Extra Alchemy's guidebook is currently broken, but the basic idea of potion-making is the same and if in doubt you can find out what a potion does by throwing it at someone.

William Wythers' Expanded Ecosphere generates more varied biomes without adding any new blocks, and it (along with everything else) should be well integrated with cobblemon.
