Another effect of the double mice can be an unfortunate one in Sunken City: If you use a Jet Charm to reach exactly the position you want to go to, the Valentine's mouse releases another jet charm, which may cause you to fly past the place you wanted to reach
I listen to Feedback Friday this afternoon, and it was suggested that if they repeated this event next year, they might consider to keep the Valentine's mice out of certain locations for such reasons.
It was also mentioned that the encounter rate of those mice was about 20 %, so you could expect to catch one mouse per hour. I went on a tourney this morning, and during 4 hours I only caught 2 - a little DHU is only to be expected. I still got into the top 25 % in the tourney and got a small pile of charms - nothing great or big about the rewards from these small tourneys. I don't know whether I'll be bothered to join another one.
I'm hoping to silver one or two of the Valentine's mice, and it's also a good opportunity to run around and crown other mice fromtreasure maps. I'm also finally working on bronzing the Ringleaders in Claw Shot City - a lady on the forum needed someone to work with, because she needs Fool's Gold for a trap, and the Wanted Posters are a good source for that. We need to do between 10 and 20 posters, and it's a good thing that they can stay open and unattended while we do event maps instead. I'd rather not do 20 posters solid ...
