1) The most unrealistic thing to happen this entire arc is having the Shandorians be instantly cured after a single shot (yes this includes Conis’s dad surviving being struck by lightning)
2) tattoo alert
3) Dancing shadows are an important, recurring visual motif throughout the arc, starting way back in Jaya. First when the Straw Hats make friends with Cricket and the monkey brothers
Then there’s the Straw Hats dancing around the fire before their big gold hunt, the Shandorians celebrating their victory over disease now during the flash back, and finally at the very end of Skypiea when Luffy acts as the link between Shandoria and Skypiea
And of course, let’s not forget seeing the shadows of the Shandorians was the kick start this saga, and Cricket seeing Luffy in the sky acts as a sort of thematic end cap as well.
All that to say, yeah. Shadows are important to Skypiea
