Tobirama eyes Shukaku for a moment. He's not regretting making friends with the bijuu or inviting him along on their coming trip since the bijuu has been so helpful but he admits he hadn't really thought through the logistics of traveling with a Bijuu. You know, those demons that are taller than mountains. They've attracted followers. They haven't even left Suna yet and they've attracted followers. The Suna shinobi are trying to be stealthy. See, it would probably work against literally anybody else but Tobirama is fairly sure that he's the most powerful sensor in the world, at the moment. He's known for being a sensor, as well, even if the rumors don't know how powerful his ability really is, but shinobi should know better than to try and follow him. Although, Shukaku's overwhelming chakra does make it a bit difficult to locate exact positions and numbers...

"Is it possible for you to... thin your chakra?" He asks. "We are attracting a lot of attention and I wish to make sure they don't aim to harm you or me." Thinning isn't the proper term, nor is it entirely accurate, but Shukaku acts enough like a child that he feels the need to simplify his words. It's likely due to the Ichibi's ignorance regarding humans. If his friendship with the bijuu continues, he's going to have to teach Shukaku human traditions so that his human acquaintances will be just a bit less on edge.

"I don't think so," Shukaku chirps. "But! I can do this!" Tobirama stops when the bijuu does and he turns to Shukaku, curious. The Ichibi squeezes his eyes shut in concentration. A moment later, with a flicker of chakra that reminds him of a henge but somehow more solid and a puff of smoke, a young boy stands before him. Tanuki features are still obvious, with the patterned fur, ears, eyes, and tail, but it could easily be passed off as a Kekkei Genkai.

"I can also turn into a small tanuki," Shukaku explains as he latches onto Tobirama's arm.

"I wasn't aware," he admits. It's a rather large oversight, considering he had already lived through these years, in his original dimension. Although, he had also been in Konoha for most of that time, unable to follow his more complicated scientific pursuits.

He'll need to buy (or build) a lab after he's finished with this whole chakra leech mess. He's almost desperate for something more interesting to do.

"How'd you think we got around everywhere without humans noticing? We can't teleport..." Tobirama shrugs at him.

"I wasn't ever sure. Bijuu only come through the Land of Fire every once in awhile and I had been... preoccupied." You know, with the war and all. The Bijuu probably don't pay attention to humans enough to know about the war, so he's just not even going to mention it. Of course, he could be completely wrong but he blames all of his excess caution on Shukaku's even more child-likeness.

"Kokuō's the best at it! He can hold it the longest and he looks the most human when he transforms."

"Interesting," Tobirama says truthfully as he starts walking again. It prompts Shukaku into taking the lead again as he chatters on about his siblings. Mostly Matatabi and Kokuō, who he's starting to think is the Gobi.

It's nice to know that one of the bijuu is a pacifist.
