Yes, it's the blue liquid! your villager gains some skills but witch one, that is random!
Generally,the blue liquids have good effects, the fizzy have bad effects and the red liquids are very bad!

But take care of the oily blue liquid: your villager will become very young but if it's a girl, look what Lady CFII wrote:

I'd need help for this event: "The visitor (in a boat) want to gather samples". I know what happens when we agree but not when we refuse! Does somebody know it?
Thanks in advance!

You can look here, Laurence. There's a good writeup in the post by JimmyNexus.

Thanks a lot Barbara!! I didn't see this topic (it's dated from more than 1 years! ) It's very helpful!!

You can search for up to 2 years, but there is actually a way to search the entire forum! If you don't find anything within the last 2 years, all you need to do is remove the entries in the "Newer than" boxes on the Search page and put 2 years in the "Older than" boxes and it will search everything else.

Thanks Barbara!

This is (in PDF file), the events that I have listen in VV1

VV1: A New Home - Events

among my own experience and also the hints I found on the forum (especially with the help of Kittenangel2001 and JimmyNexus )

if you find it good enough, maybe Barbara could put it on VV1 guides?

Laurence, please see this post about submitting material for the Guides.

Thanks Barbara! I have sent it
