They sailed all the way up the dazzling Rainbow Bridge, and before long, the scenery of the Sunny World slowly unfolded before them.
The first thing they saw was a shoreline with a beach. Clear spring water gushed from tree hollows, cascading down layer after layer like waterfalls into the bay below.
