Abstract: A jungle gym requiring a small storage space and easy assembly is provided. A jungle gym comprises a main frame body comprising connecting bars extending vertically or horizontally. The main frame body has a shape of an approximate cube or an approximate rectangular parallelepiped as a whole by connecting the connecting bars. The jungle gym also has a sub-frame body being attached to the main frame body and turnable around one of connecting bars of the main frame body or around an axis being parallel to the one of connecting bars. The sub-frame body is capable of folding along the main frame body.

Abstract: An electronic musical toy instrument has a first memory unit for storing a lot of music sound data for playing music, a second memory unit for storing sound data that corresponds to a sound responding to the progress of the music, a sound output unit for generating sound that corresponds to the music sound data or the sound data, and an operating member for reading the sound data out of the second memory unit. With the electronic musical toy instrument, a sound that corresponds to the sound data is generated from the sound output unit by an actuation of the operating member.
