Significance of Coconut Ice Cream

Linus knows Audrey's favorite ice cream is coconut flavored and that the ice cream truck in the park does not carry it, but he goes to extra trouble to get the man to carry it for one day as a special treat for her. This gesture with the coconut ice cream symbolizes what Linus wants to provide for Audrey in their relationship. He wants to provide her with treats, to give her something she loves, and most importantly, to show her that she is worth having the things she loves.
