This was the first adventure to have event items appear outside event maps, and to feature shops where you could choose what to purchase.
Maps[]
Sometimes a map has a randomly placed event item in it which could be collected to purchase items in one of the four shops in the event map. Once collected on the maps, event items will appear on your back and won't be obtained until you bring the cheese to the hole. You can spend these currencies on the event map in the shop listed below.
A mouse carrying a collectible (notice how it'd lie behind the cheese).
Five seconds has to pass before you can collect the event item on a map. If you are revived by a shaman using the Ambulanceskill after collecting an event item, you will still have the item when you respawn, negating the need to collect it again, despite the fact it no longer appears on your back.
BugThe NPCs in the event map do not show up in survivor rooms.
BugIf you've got the event item before getting revived, you will not be able to see it until you get into the hole with the cheese.

Four-Leaf Clovers are tradeable, but not Pots o' Gold and Lucky Horseshoes. This may or may not be a bug.
Rewards[]
Shops[]
These rewards could be bought using the event items gathered from maps.
In Transformation maps with an event item in it, transformed mice would still be shown holding the event item if they held it before transforming.
The Paintbrush item is seen as controversial by many people because of the ability to draw inappropriate things and words without the ability to hide the drawings, like you can with whispers and stationery paper.
The fraise fragment system was also added to the game around this time.
