My go at a translation: 1: Marisa: Reimu! Little ones! Everyone listen ze!
2: Marisa: The human is now changing his residence!
3: Marisa: Humans are stupid, so I say we go for his house ze! So we break through the front and occupy it. Somebody should lead ze! Yuyu! I nominate Reimu's Marisa! The little ones will surely be able to take it easy!
I don't have the exact translation down but the basic gist goes something like this: 1 Marisa: Reimu! Kids! Everyone listen!
2 Marisa: We're going to move into mister human's house!
3 Marisa: Because mister humans are stupid they won't understand when we declare it ours! (not sure about that sentence) Therefore we will break through the front and capture everyone without complaint! (or without a word, not sure about this translation either) Reimu: Yuyu! As expected from Reimu's Marisa! The little ones can also take it very easy!
