Response: To upgrade all of Oatchi’s skills in Pikmin 4, follow these detailed steps:

1. Rescue Captain Shepherd
– Begin your adventure and rescue Captain Shepherd replica watches early in the game. This will unlock the ability to further enhance Oatchi with various upgrades and new abilities.

2. Meet Oatchi
– After rescuing Captain Shepherd, you’ll meet Oatchi, who is an immediately useful dog-like companion. Oatchi can pluck Pikmin, jump onto low ledges, dig for treasures, and replica Breitling rush enemies and environmental barriers.

3. Understand Pup Drive
– To upgrade Oatchi’s abilities, you’ll need to increase your Pup Drive by completing missions and dungeons. Pup Drive points are earned by rescuing castaways, winning replica Rolex watches Dandori Battles, completing Challenges, and using Glow Sap.

4. Upgrade Oatchi’s Skills
– Once you have enough Pup Drive points, return to Shepherd at the Rescue Command Post to rank up and upgrade Oatchi’s skills. Here are the steps for each skill:
– Buff: Allows Oatchi to push boxes and carry treasures. Upgrading Buff to Super Buff boosts the strength that Oatchi has learned with Buff.
– Super Buff: Each level of Super Buff costs two Pup Drive points. At levels one and two, Oatchi gains the strength of 20 and 30 Pikmin respectively. Super Buff level three grants Oatchi the monstrous strength of 100 Pikmin.
– Chomp: Oatchi’s standard biting attack. Upgrading Chomp to Big Chomp allows for a stronger bite attack and the ability to jump and attack.
– Big Chomp: Allows for a stronger bite attack and to jump and attack. Maxing out Chomp and then Big Chomp costs a total of 13 Pup Drive points.
– Rush: Oatchi can charge and rush forward breaking objects or damaging creatures. Upgrading Rush to Mega Rush makes Oatchi’s Rush ability stronger and allows him to defend against enemy attacks better.
– Mega Rush: Each level of Mega Rush costs four Pup Drive points. Level one lowers charging speed and stuns large enemies, level two increases damage dealt, and level three rewards a longer stun duration and more damage.
– Doggy-Paddle: Allows Oatchi to swim and carry Pikmin on his back through the water. Upgrading Doggy-Paddle increases swimming speed.
– Doggy-Paddle Level Three: Each level costs two Pup Drive points, and level three allows Oatchi to swim faster than a Yellow Pikmin.
– Dig: Oatchi can dig quickly when this is upgraded. Each upgrade only costs one Pup Drive point, and level three allows Oatchi to dig even faster than a Yellow Pikmin.
– Heal: Allows Oatchi to heal faster. While Scrummy Bone will still be most effective for healing, upgrading Heal increases passive healing speed.
– Command: Increases the number of things that Oatchi can track down using a scent. This skill is useful for finding lost Pikmin and tracking items.
– Swallow: Oatchi can carry treasures/creatures that weigh up to 100 in his mouth. This skill is unlocked through the story and must be purchased from Shepherd.

5. Max Out Skills
– Most abilities have three levels to reach, and once you’ve maxed them out, you’ll unlock a super version of that skill which will make Oatchi even stronger.

6. Additional Tips
– Focus on upgrading skills like Buff and Super Buff first, then Rush and Mega Rush, as these will make it easier to carry larger treasures and tackle creatures from the get-go.
– Use Pup Drive points wisely by completing Night Expeditions and rescuing castaways to earn more points.

By following these steps, you’ll be able to upgrade all of Oatchi’s skills in Pikmin 4, making him a more powerful and versatile companion in your adventures.
