Translation:The mouse steals my brother's rice pudding.
Risengrød is a rice porrige, risalamande is a pudding dessert made with risengrød, whipped cream and almond slivers. It's eaten as part of a game played during Christmas and new years. Whoever can find the whole almond in their pudding wins a prize, traditionally a marzipan pig
This sounds like a crime wave all these animals stealing peoples food those poor Danes.
