Iru Mono to Iranai Mono (E79)

Fenny gives Bonobono a Togebonbori which really hurts when you squeeze it under your arm. Bonobono tries to put it in the tree where he keeps important things, but it's already full. His father tells him to throw away what he doesn't need. Some things he doesn't need today, but might need tomorrow. Others he needs today but might not need tomorrow. It's hard to throw things away.
