Tarantula Island. How many times have you been there?

I got 80 NMTs. I landed there 6 times with all 80 NMTs.

If you land on tarantula island, after you have it cleared of everything, go to the middle part where it's a circle.. stay near the edge and walk in a clockwise direction. If you see two of them, play red light green light with them. Eventually one of them will walk off..

Leaving only one of them playing red light green light with you.

Twice

Actually, if you use a shovel to make a narrow corridor in the centre, you can somewhat safely catch as many tarantulas as you want without being constantly bitten by them. I find the tarantula isles at least once a week depending on how many NMTs I use.
