Building Bridges
"Building Bridges" (formerly known as Furnishing for Friends) is a "The Right Tools" quest that unlocks the bridge to the 
Cozy Islands and is a sub-quest for the "Power Up the Gate" quest. The quest is unlocked when the player is working on completing the "Power Up the Gate" quest.
Quest Description
"Set up a Visitor Cabin so that new friends will come to Friendship Island."
Quest Information
In order to obtain the third 
power crystal for the "Power Up the Gate" quest, the player must interact with the billboard near the broken bridge north of the Resort Plaza with 
Chococat. 
My Melody will talk to the player and ask them to find two 
Strawberry Crates. After finding the crates, the player needs to return to the billboard in order to build a bridge to the Cozy Islands. My Melody will then repair the bridge to the Cozy Islands! (The final power crystal can be found on the Cozy Islands, but this quest will end after the bridge is repaired).
