I found that the Italian Super Mario Wiki has an article describing a Boo exactly like Bootler, but it uses the name "Boolindo", not the "Booregard" we're having in our foreign name box. A gossip-loving Toad (Talk) 04:28, 15 June 2016 (EDT)

Interesting. Before we change it to "Boolindo", does anyone know what kind of word play it is? Mario (Santa)'s map icon from Mario Kart Tour Mario-HOHO! (Talk / Stalk) 20:11, 18 June 2016 (EDT)
To quote Wiktionary, wiktionary:lindo:
lindo m ‎(feminine singular linda, masculine plural lindi, feminine plural linde)

1. neat
2. clean
3. tidy

Don't know whether "Boolindo" might be a portmanteau of something else. -- A gossip-loving Toad (Talk) 06:26, 5 August 2016 (EDT)
