Instructions
Play past Levels 1 through 8. Dino Jungle is the ninth level of Kirby's Epic Yarn.
Walk down the water dinosaur's neck to get to his head. Pull the buttons and jump off the dinosaur's head to a hidden area in the green wall directly in front of the dinosaur's head. These are the hidden beads within the level.
Continue through the level by riding the water dinosaur. Collect the beads you see along the way. After the first green wall, there are no more hidden beads in this particular level.
Complete the Dino Juggle level by jumping through the T-Rex's open mouth. Go back to the main menu, visit the shop and exchange your beads for a sofa. You need 500 beads to buy a sofa.
