Yeah, it was with villagers. One of them went to get two other villagers and I had 15 minutes to find them and I got a prize for doing so.
And I'm actually kind of disappointed in the new tarantula/scorpion mechanics. I understand why they changed it, but at the same time, it makes catching them amazingly easy. Just get far enough away, pull out the net and they'll run right for you and you just need to press A at the right time.
The WW mechanics worked in such a way that the AI was quite random and unpredictable, which made catching them more fun/challenging. I was damn proud of my trophy room filled to the limit with cages containing scorpions and tarantulas in WW. I just don't know if it'll have the same effect in CF.
