I've been wondering about this translation ever since the tent was added with Dream Home Decorator but I couldn't figure out what it was supposed to be. Now I think I've finally figured out that it's supposed to be "play inside". "Indenfor" is a correct translation of "inside" but it can't be used the same way as it can in English since it strictly refers to being inside a house (so when it says "leg indenfor" it reads as "play inside the house" to Danes and not as "play inside the tent").
A way to translate it could be: "Leg i teltet" ("play in the tent") or "leg inde i teltet" ("play inside the tent")
