Ok guys here is a picture of the three bunnies' poops. From left to right it's Lulu's poop, Moomoo's poop, then baby Bamboo's poops (she's 3 months old). See how much bigger Lulu's poops are than the other bunnies??? It's like almost twice the size of Moomoo's poops and Moomoo is a bigger bunny.
Here are Moomoo and Lulu (Lulu is the white one). Moomoo is not quite as long as Lulu but she is definitely a heavier bunny. She's wider and stockier.
And here's Bamboo. Can you believe it she flopped against my leg! I've never in my entire life had any bunny do that to me. She's probably 3 pounds now.
