Original Wooky consists of two files: (1) splash screen, and (2) game file. Splash screen contains definition of characters, so it is not possible to run only the game file. This is problem when Wooky should be started from different medium than CMT (cassette magnetic tape).
Shrunken Wooky file that contains both parts can be downloaded here: Wooky-all.mzf
