The Polarian Bundle house is one of my favorites of all time. Part of it is a good amount of tricky areas for making the hide and seek games fun. Part of why I like it is the comfort factor and part of it is hidden areas! Of which there are a few. Every house needs a secret passageway or two or three!
Anyway, this is a fun place with ice on a lot of areas including part of the house. The ice makes your mount/whale/skates fun by making them about twice as fast on the icy parts.
Ok. here is a video of the grounds and house and a guy that's camping out under your house giving out pet snacks and what not. A bit weird I agree, but at least he gives you something... Check it out.
(The videos are in the approval process but should be released shortly. If they don't render within a minute then come back in a few hours and they should be live...)
Then a secret tunnel and secret blind wall exit.
Last but not least the secret ice fishing cave.
This bundle has some cool items that are just plain enjoyable. For example, I like that when you jump while mounted on the whale that it turns over and your character partly falls off and gets back on. Of course I love that your mount can give you extra tough albeit a very small amount. That's awesome! And I love the touch of the ice and the fact that it feels kind of slippery.
