I've had:
an airtight crate that had three babies in it
an old drum found in the jungle that had a journal in it, made the person a master scientist.
an old crate that had old tools in it, got tech points but it made a bunch of people sick
a monkey stealing food, scared him off and person got mauled (not killed though)
a monkey stealing food, followed him and found 2000 bananas
a monkey messed the research table and lost 9000 tech points
a scroll that with the story "The secrets of Isola" whoever reads it disappears into the jungle
The North Wind -replenished the berry bush
The South Wind- destroyed the crops, berry bush and rotted the stored food

I think that's it!
