The type with a light-up nose (the mechanism differs depending on the character, making it a bit educational) doesn't light up for Anpanman and Melonpanna-chan (the left two) because the batteries are dead. The Kokin-chan gachapon-style toy originally contained small balls, but they've been removed and discarded due to the risk of accidental ingestion. The Lego-style Melonpanna-chan and Baikinman are dolls from the popular toy series "Block Labo" and are perfect for playing with as they have movable hands, feet, and heads. They also come with rolling parts that can be played with in conjunction with the "Block Labo series" toys.
