StoneKirby and Rick are rolling across some rocky hills towards Coo, who is perched on a stone connected to a rocky wall. Kirby and Rick crash into the wall and Coo and the stone fall onto Kirby. Luckily, Kirby is still in his Rock-form so he isn't harmed. They all sigh with relief when they see that Kirby wasn't hurt.
Red Canyon is a barren, mountainous area in Dream Land, and is one of the seven Rainbow Islands. Red Canyon's craggy environment is diverse - there are sandy badlands, deserts, caverns, and many different rock formations. It has huge water-filled tunnels underneath its surface. It is known for its red-colored rocks, which Red Canyon is named after. While not directly appearing in Kirby's Dream Land 3, Kirby travels through Sand Canyon, a similar level in terms of its name and its scenery, and bosses (both level have tag-team styled bosses). Collectively, Mr. Shine & Mr. Bright make up the boss of this level.
Surprisingly enough, Stage 5 of Red Canyon contains groups of Star Blocks in the shape of a naked woman. This was effectively hidden because the screen isn't large enough to display all the blocks at once. The full image was eventually revealed in a Japanese guidebook.
In terms of geography, Red Canyon is somewhat like Yogurt Yard. The two levels even share the same music.
