Realm of the Chomp
You could've visited Chompshire at any time after the Rubadub gained the ability to fly, but this is the perfect time to take advantage of it. To reach this secret village, fly towards the Yulyana region to the north-east of the Harena region.
Next, land at the west side where there's a gap in the forests or by the pier along the north-east side of the central lake. From there, head through the forest on foot towards the south-most edge of the continent. Once there, you should spot a small gap in the trees--this is Chompshire.
Inside the hidden village, head west along the path towards the plush chomper factory. Inspect the big chomper in the corner of the viewing platform for a dangerous Bomb Fragment . Afterwards, contine down the path to reach the rest of the village.
If it interests you, speak to the owl in the south-west corner for the option to change your characters' names . This has zero importance to the plot, but imagine all the laughs to be had when your characters are called Me, Moon Girl, Mrggr and Bob.
Anyway, you'll find everything important along the east side of the village. Here, you can purchase every Level 1 to 6 magic scroll from the Magics store, Elixirs from the Trader and various equipment from the Armory. Also check the area left from the boat for a Leviathan Sashimi .
Bonus Items : From Chapter 5 and onwards, the Armory will stock the Growth Egg, Golden Egg and what we like to call "cosplay equipment". All of these items are pricey as heck, but that's nothing you can't solve by grinding at Grapp Keep or your favourite grinding spot.
Recommendation : Definitely consider investing in the Growth Egg for double experience and job points and the Golden Egg for double pg. Sadly, you can't equip both at once (unless you want to earn nothing from battles), but double of anything is pretty amazing!
