Cannot find toxic lake

[etsubmariner]

Got a quest to throw a little Creator action on a toxic lake. However, all of the lakes on the planet were 0% toxic according to the game itself when I clicked on them. I then thought maybe to just fire off Trickle Down on the one next to where my nuggets live, which wasn't toxic, and of course that didn't do anything. Quest failed. Uh, what?

Bigger question I am running into -> sometimes the quests ask me to find a particular thing or nugget. HOW do I find specific nuggets in a one stop/one shop panel? How do I find the specific toxic lake? Need some help here as a newbie.

The thing you're meant to find is often highlighted somehow. Or you can click an icon on the right of the panel giving you the quest. It's not top right or bottom right, but look on the right side.

To find a particular villager, use the villager list, which you can get with one of the icons on the top right of the screen. Then you can scroll down till you find that villager name, then click on the task icon and pick 'find me' or whatever it's called.
