Now I understand how Shino can control his weight with his bugs: apparently they're filled with helium, since crystallized bugs float in midair.

Weren't the bad guys able to transform into monsters? Actually, I got the impression that they were "monsters" in their original form, but transformed into human form. Thought we would see at least one power up from them.

Finally, I don't see why they (Konoha) didn't have a team to protect the sealing team from the start.
