Eternal Dreamland comes about when Queen Sectonia merges with the Dreamstalk after her defeat, causing the plant's vines to grow out of control; they cover the Planet Popstar's surface so Sectonia can feed off of it forever. Kirby and King Dedede panic, but the People of the Sky soon bring them a cannon to fire through the foliage.
In the first part of the level, Kirby has to shoot the one-eyed flowers growing on the Dreamstalk. The player aims him with the Nintendo 3DS gyro. If Kirby hits part of the Dreamstalk, gets hit by an exploding seed, or hits a closed flower, he will take damage. When all of the flowers are defeated, Kirby must quickly be shot to Sectonia. He then reaches a vine walkway with many 3D Warp Stars, Copy Essences, and Bandana Waddle Dee ready to toss an Assist Star.
Kirby then enters the second part of the level: The final bout with the Dreamstalk-fused Sectonia. This battle consists of five phases, each one harder than the last. In the final phase, Taranza reappears and tosses Kirby a Miracle Fruit, transforming him into Hypernova Kirby. He must then inhale seeds launched at him and spit them back at Sectonia's flowers (once again aiming with the gyro). When the tyrant is finally defeated, the Dreamstalk's overgrowth fades away. Eternal Dreamland is destroyed and Floralia and Planet Popstar are saved.
- In the French version of Kirby: Triple Deluxe, Eternal Dreamland is called Effrayant Sanctuaire -- "Scary Sanctuary" in French.
