The Snake Rocks, Snake Stump and the Hollow Snake Trunk do much more than just produce snakes. It’s something a few readers have noticed and while I’ve mentioned it in comments, I hadn’t realized that I’d never done a post on the best-kept secret about the snake-generating premium items until this comment came in from @Landaasen:

The snake rocks, stump and trunk are all 2.5% multipliers (I took them in and out of inventory while collecting white houses, and it seems about right). This is a pretty important detail, especially for those who are a bit behind and getting sweaty, and considering a purchase. The question is why this is β€œsecret”; if it is permanent, or just a bonus effect during the Whacking Days. Considering the cost, this should be permanent, making them attractive multipliers.

I have a feeling that the bonus multiplier effect will be permanent – as they already carry a 2.5% bonus multiple I can’t see them suddenly changing to Vanity-rating decorations once Whacking Day is over. And that means the snake-generating decoration do three things – they generate snakes, they give your friends an extra item to tap on to collect cash (during Whacking Day, at least), and they also earn you an extra 2.5% on money and XP earned through rent and jobs.

Update: It may be that you don’t get this multiplier effect from the free Snake Rocks.
