How to unlock the That's a big backpack! achievement in Yoku's Island Express - Definitive Guide

When you open up your inventory/backpack, you'll see a grid of items on the left and another on the right. This achievement requires you to obtain all items on the right grid, and all of their upgrades. These items are as follows:

  • Noisemaker: Story-related
  • Kickback: Story-related, but if doing this achievement after completing the game, you'll need to reacquire Kickback. To do so, take the northern beeline up to the top of the snow area, but get off the beeline two stops before the end. Drop all the way down to the ground and head right into a cave to find him again
  • Sootling on a Leash: Story-related
  • Dive Fish: Story-related
  • Slug Vacuum: Story-related
  • Fast Dive Fish upgrade: Awarded upon completing Willo's side quest. Refer to "How wonderful" for more information
  • Slug Vacuum Deluxe upgrade: Awarded upon completing Rinri's quest. Refer to "Spreading spores" for more information
  • Skvader: found in a random chest or crystal. The "Treasure hunter" achievement solution has more information on chests
  • Fat Skvader upgrade: found in a random chest or crystal. See above
  • Grand Postmaster Badge: awarded upon delivering all packages and letters. Refer to "The mail always gets through" for more information

The items on the left side of your backpack, such as the wallet upgrades, treasure map, etc., are not required for this achievement.
