Panels 5-6 were cut from the final version.
The drawings and the fact that it's a creature make me think it might be Anai's work. The drawings are very different from Miyamoto's from the same part, so it's definitely not him; and considering the guidebook notes that Anai had to double and triple check designs and concepts from even the storyboard stage make me think he probably might've corrected this part(?).

Either way, I don't feel like presuming based on anything I said.
