Spoiler for beast:

Are bijju's even know that they were part of the ten tailed beast - juubi is manga material, so the anime-only viewers might be spoiled

Well the scroll/frog is a key, Jiraiya left to Naruto. It's purpose it's to seal or unseal the nine tails chakra inside of Naruto.

Spoiler for narutopedia:

Gerotora (ゲロ寅) is a "scroll toad", a rare species that closely guards whatever secret is written on its scroll-abdomen until his contractor dies. He resides in the body of his contractor, and is known for his excellent endurance.

Gerotora guards the scroll which acts as the "key" to the Eight Trigrams Seal on Naruto Uzumaki's stomach. The key is left to Jiraiya after the death of Minato Namikaze, and Jiraiya in turn leaves it to Naruto when he dies. Gerotora voices his concern about this, pointing out that the key is being left atop the very "safe" it opens. He also does not think Naruto is ready to tamper with the seal. Jiraiya said that Minato gave him the key's jutsu design as a sign that Minato intended Naruto to complete an unknown jutsu.
