Yes for the first part of the special its not there then its as if for the last 1/4 of the special someone just decides to put it on him, I don't get it. I also don't know why they decided the change the color of the sword, as I've said before the anime seems to randomly change the color of things but the sword in the manga just looks so much better. How they ruined this is akin to how they ruined Kakashi's MS scene.

Seriously it seems the last thing the anime got right was the Gaara vs Deidara fight. There is one other major change that they made that no one seems to have noticed but I'll talk about that some other time.
