Two Point Campus

Do this on the archeology map, Pebberley Ruins. I believe their respawn is faster here. Do not buy any land until you complete the achievement. Make the building creation in about 80% of the terrain and leave the rest for open field, make sure you can have the open terrain in the field of view of your screen.

Here their respawn is practically instantaneous, you should be able to accomplish the achievement between 15 to 20 minutes at most, just pay attention to the creatures respawn. Avoid leaving open field on the sides of the building because if the worm is taking a while to appear it will be in the surroundings close by.

I did it on fluffbourgh, i build a big building to fill the whole patch of land to the left of the starting building. Then i keep the grass on the right empty an didnt start the term an clicked on those bookworms that pop out of the ground.

On the level where you will learn about knights (4th school), there will be open fields to build outside classes on, try to keep 1 of the pieces of grass empty (dont build a lot on it) and more of the bookworms will spawn and you will need to click on it.

You can also buy more pieces of land to have more places to have the bookworms spawn on.

Bookworms are little worms that burrow out of the ground outside of campus buildings. They will appear for a couple seconds before digging back underground. In the time that they appear you need to hover the cursor over it and press A to interact with it. This will earn you some Kudosh and contribute to this achievement. If you're too late don't leave the area because most of the time it will resurface pretty quickly so wait around for a moment and see if you can still get it.

This achievement more than likely won't unlock naturally because the Bookworms appear so fast that unless you're actively ready for them you won't move the cursor over to it in time before it disappears. Additionally, you'll likely be looking inside a building and not regarding the outside much at all so you usually won't even notice them.

A good way to grind them out is to go to a map with a nice green field (they're a bit easier to see against green) that fits fully on screen and wait for them to pop up. A good map for this is Upper Etching because there will be two green fields that you can cycle between right in front of the campus. Bookworms don't seem to spawn if you just continuously watch the screen so start a cycle of watching a field for a few seconds, then go and do some campus management for about 20 seconds and come back and watch the field again for a bit. After catching your 50th Bookworm you will get this achievement.
