Here's a brief rundown on the events of Oh So Hero! Act 1. Spoilers ahead!
Joe goes from Sheo Island Beach, to Treewish Forest, to Southeast Beach, then to Cas's House.
Inside Cas's House, Joe acquires the “Ass Masters [Limited Edition” book, granting him the Butt Stomp ability.
Joe returns to Treewish Forest, and uses the Butt Stomp on the large cube-shaped blocks near the Goliath (large frog).
Joe proceeds downwards from the destroyed blocks and to the right to obtain the “Lono'e Natural Loob” bottle, granting him the Slide ability.
Joe rises from the Forest floor eastward through Brask's Jungle and then to Brask's Palace.
Joe speaks with Brask to obtain the Lazurlite Mirror, allowing for Fast Travel.
Joe exits the Palace and continues eastward through the Forbidden Bayou.
From the Bayou, Joe can go to Hiroto Dojo (faster), or continue east through Smol Beach and Lood City (slower).
Should Joe take the slower route, upon reaching the far east side of Lood City's West Avenue, Joe is stopped by Hamill, who demands a Red Key Card.
Joe travels to Hiroto Dojo's East Building where he finds the Red Key Card sitting just to the left of the giant vault of money.
Joe returns the Red Key Card to Hamill on West Avenue then enters Lood City Park.
Joe fights Bates in Lood City Park.
End of Act 1.
