Questions & Answers about Detrás del arbusto vimos un conejo pequeño.
Spanish is more flexible than English with word order. The most neutral order would be something like:
Vimos un conejo pequeño detrás del arbusto.
But putting Detrás del arbusto first is very natural if the speaker wants to set the scene first, a bit like:
Behind the bush, we saw a small rabbit.
So this word order adds focus to the location, but it does not change the basic meaning.
