Between 2008 and 2011, the Japanese magazine Dengeki Nintendo ran a gag strip based on Wario Land: SHake It alongside many other game mangos. The plot had Wario tagging along with a bandinero or something. It's never been collected anywhere and is obscure enough the only substantial information about it on the JP wikipedia page for Shake It. Here's a strip.
I found out about it on Mariowiki: a page was created on June 7 but I only learned of it now.
