* "Wazzat" is a corruption of the English phrase <i>"What's that?"</i> and the word <i>hat</i>. It could also be a play on words that this Yo-kai was an ordinary hat before he became a spirit (<i>"was a hat."</i>) His name may also be an allusion to the term <i>whatchamacallit</i>, a person, place or thing that is unremembered or unidentifiable ("What is that"?)
* "Wasurenbo" is a slightly corrupted version of the same kanji "to forget" (Japanese: <span class="t_nihongo_kanji" lang="ja"><b>忘</b><span class="t_nihongo_comma" style="display:none">, <i><span class="t_nihongo_romaji">Wasureru & Bō </i>) uttered twice in different reading methods (Kun'yomi and Kan'on). It can also mean "to neglect", referring to Wasurenbo's origin. It is also a combination of 忘れん坊 (Japanese: <span class="t_nihongo_kanji" lang="ja"><b>Wasurenbou</b><span class="t_nihongo_comma" style="display:none">, <i><span class="t_nihongo_romaji">"Forgetful person"</i>) and 帽子 (Japanese: <span class="t_nihongo_kanji" lang="ja"><b>Boushi</b><span class="t_nihongo_comma" style="display:none">, <i><span class="t_nihongo_romaji">"hat"</i>).
* Japanese: わすれん帽 <i>Wasurenbō</i>
