You've done some sailing, and arrived on island A4. What do you see?
Try getting a closer look.
Yeah, they've gone underground. What does Cleo have to say about this?
Naturally - is there an objective third party on the island somewhere?
Exactly, so it won't take you long to find a hint!
Read the sign on the rock.
It says, in very small letters: ?
Please don't get too close! These glowing mushrooms are very shy, and withdraw as soon as they feel pressured. Each of these rare mushrooms is connected underground to an alternate location.'
Do you have anything that could block or fill those holes?
Corks! You might find some closer to civilisation.
In the hotel, prominently displayed on the far left.
Fishing! This guide can tell you more.
It means that the mushroom can't get back - where else might you find mushrooms?
Island I4! Set sail!
Yes, they're connected underground of course! Notice anything different?
That's right, because you plugged up the hole on the other island.
You talked to someone who was interested in mushrooms earlier.
They were close to the corks you shamelessly stole.
The hotel guest that was writing in her travel diary! Set sail for the hotel!
