Yes and it can scare the bejeezus out of you if you have your sound up.
That’s called Boolprop. 
You can also bathe them in the tub for Water. 
About to spoil the heck outta the game:
I am so in love with this game right now. I’ve had it for a week now and I still smile and get all misty eyed when the snow starts falling. I was actually beginning to get worried that I was getting bored with my Sims, but Seasons makes the game so much more random!
Winter has been the most fun for me, probably because being in Florida I never get to see any snow. First thing I did was set my hood for Winter, Spring, Summer, and then Fall. In the winter you can really build up family relations - they get a big social boost then and roll up a lot of family-type Wants.
I love the added challenge of keeping their temps just right. Don’t watch them in the hottub and they can spontaneously combust. Leave them building snowmen for too long and they can freeze solid. I tried to freeze a vampire around sunrise, but unfortunately he was abducted by aliens before his temp dropped low enough.
Fall is amazing with the colors and leaves falling (though they can be a pain to keep up with raking, if you care about outdoor environment score). Fall gives a huge boost for skill learning. When a Sim studies, the meter above their heads get swirling leaves around it to show you’re getting a boost.
Summer looks pretty much like standard ol’ Sims pre-weather, but you get some showers occasionally and it is easier to build up friendships. The new water effects on the pools are amazing and I love that you can now change the pool walls and floors and have rounded corners. Also, watching them play Timle Torneau is too cute - they’ll actually do a ‘fish out of water’, sneak around the pool and jump back in. Speaking of ‘jumping back in’ they can now do that! Don’t worry - ladders are still required for getting out. 
Remember earlier discussion about needing a ‘leftovers’ option? Yes, there is one now. 
You click on your half eaten plate of food, or the platter of sandwiches and ‘Put Away Leftovers’ which can sit in your fridge indefinitely and can be retrieved and eaten by children without an adult having to fix it for them.
I adore the new fishing ability and frankly I thought it would be the last thing I’d have my Sims doing but it is fun to see all the different fish you can catch, the different meals they can make with them, and it is definitely a bonus that fresh food fills hunger so quickly!
I’m also having a great time with one family that has a garden and some orchard trees. The mom stays at home and tends the greenhouse all day. You can sell the produce for simoleans, give them as gifts (also new interaction!), stock them in your fridge, or juice them. You can also juice the boot you can catch by accident while fishing - hilarious!
PlantSims - directly related to the Jolly Green Giant, if you ask me! I gave mine freckles and she looks so cute! I’m a little disappointed they only have 3 life stages; Toddler, Adult, & Elder. I think if a male PlantSim was abducted by aliens then it would be a standard alien pregnancy since they only reproduce PlantSims asexually by sporing them. Like with Vampires, if you get them pregnant by conventional means, you get a regular Sim baby.
The spores of happiness are fun though.
I love the rain. I’ve always enjoyed those nature-type soothing cassettes with rainstorms. It is very relaxing to listen to the thunder rumbling in the off distance with the rain pitter-pattering on the leaves and ground. 'Course, just as you’re lulled into a sedated, cozy state watching your Sim reading to their child in front of a fire is about the time a huge bolt of lightening strikes the tree next to the house, setting it on fire and almost causing you to piss yourself.
I haven’t even been through all the new objects that came with Seasons, though I have tried out the ice skating and roller rinks.
Dogs can now eat the snow and it is too funny to watch a small breed dog trying to relax on the ground - they almost disappear under the snow!
Wile E - I know what you mean about having to have your hacks! One that this game needs (if you have Nightlife) is a hack to keep the vampires hammered in their coffins so they don’t keep jumping out to go look at the pretty snow and burning. I have the smart coffin hack from DJS, but it is not updated to stop the ‘oooh, snow’ action from raising them up. I’m surprised with how quickly the hacks were updated for Seasons! I’m missing one, maybe two hacks that updates are still pending for, but that’s it.
I have to admit though, I like the fact the Toddlers can eat from the pet dishes - it fills their hunger and my Sim parents don’t have to get out of bed before they are ready just to grab a bottle.
