Question

What is unusual about the attachment of the tongue and what are its advantages?

Answer 1

Not sure if this answers your question, but the most unusual feature of the tongue is that the tongue muscles, unlike other skeletal muscles in the body, induce movement without the need of bones, in a way similar to tentacles or elephant trunks.

The advantage is that it allows the tongue to be very flexible, which is necessary when you're churning food in your mouth.
