Welcome to BB, and it’s wonderful to hear you have invited a young rabbit into your life. I hope these forums will help you and your rabbit grow happily! No one is ever 100% prepared for rabbit ownership; it’s a learning process and these forums are a helpful place to go to, especially when you’re unsure.
You are describing behavior of a rabbit settling in and getting acquainted with their surroundings. Wick does the “army crawl” (that’s what I call it) when he’s going under low-ceiling nooks/crannies, or if he’s “scoping out” a situation (i.e. rounding a corner to find food). The flooring is a bit part of it. Rabbits take some time to acclimate and adjust to smooth flooring, which is one reason why having a lot of soft, solid flooring is recommended. Navigating on smooth flooring requires some more active thought and foot work for rabbits, so initially, a lot of rabbits will avoid slippery floors all together.
