Recently he unveiled an original figure - the Eel Cat. The same size as a fortune cat baby but mutated with a distinct caricature of the japanese eel - a popular creature in Japan. I am sure there is a nod and wink to the Eel Dog character from the manga work Tensai Bakabon by Fujio Akatsuka. The versions available at Altr. Tokyo will have 柴又 (Shibamata) on the coin and the versions available at Shinto Gangu wil have the characters 青砥 (Aoto) them.
Just in case you didn't have enough stuff to collect.
