How to make it so players can collect berries?

I'm making a game, and one of the quests is grabbing a nearby Berry on the bushes. How would I do this?

Tools available:

• Monitor what their mouse is hovering over (mouse.Target)
• Use ClickDetectors
• Use humanoid.Touched

Whatever system you use, you will of course have to update the quest when the desired outcome occurs.

I suggest you learn to script. Just from the question I get the idea you haven't even tried learning lua.
