dildo?

The size and shape suggest "dildo" to me. Especially when I look at the photographs of the different angles and the video review on the product page. I imagine it would be okay to use anally if you were very careful, but it's not really a plug. I don't know how easily those bulbs would slip in, but I wouldn't take my chances - best to keep a hand on it!

Yes, it's a dildo. Just an odd shaped one.

Haha, it is a bit of an odd one!
