Once by Sun, Twice by Moon (Sun and Moon)

Exploring Akala Island up through the first trial was nearly identical between the two versions, so it goes into a single post.

Arriving on Akala Island, Kukui, Lillie, Hau, and the character are greeted by Olivia and Mallow, and explain about the first trial beyond the Paniola Ranch.

After they leave, We go through Heahea City on the way to Route 4, but first a stop at the Tide Song Hotel, where we meet Sina and Dexio. 

The PokeFrench are weird 

In Sun, I battled Dexio and got the Zygarde Cube and in Moon I battled Sina. 

Battling through Route 4, we reach Paniola Town. At this point in Moon, everthing has evolved and is in its second stage. In town, we battle Hau and is two Pokemon in Sun and four Pokemon in Ultra Moon. 

I'll show you, newbie! 

After beating Hau, we traveled through the Paniola Ranch and Route 5 to reach Brooklet Hill, the sight of the trial. 

The Trial functions the same, chase the Wishiwashi down to the bottom pool to summon the Totem Pokemon. What's interesting, in Ultra Moon as soon as you enter, Lana introduces herself as the Trial Captain and the trial starts right away. In Sun, she introduces herself like this... 

...giving no indication that she's the Trial Captain until right before the Totem Pokemon. Time to battle the different Totem Pokemon of Brooklet Hill! 

eep 

These guys are certainly bigger than the last set of Totem Pokemon, but you know what they say! The bigger they are, the more they scare me! 

Anyway, Rattata in Sun evolved before the battle with Wishiwashi, which helped in that battle. Against Araquanid, Grovyle Leach Seeded it and then Jolteon electrocuted it. 

Hopefully the games diverege a little bit more moving forward, otherwise I might do more combined posts of the games.
