Binary package “xcowsay” in ubuntu bionic

Graphical configurable talking cow

 A GTK+ version of the classic cowsay Perl script. It displays a cute
 pop-up cow on your desktop with a speech bubble and some customizable
 text. There's also a dream mode where the cow can display images. It
 comes with a fortune(6) wrapper script, xcowfortune, which you can
 cron to deliver periodic fortune cookies via the cow.
