Halloween came early this year thanks to Mabo Dofu (麻婆豆腐), who dropped a full cover of Happy Halloween (ハッピー・ハロウィン) on October 28 — right in the sweet spot before the actual holiday. The original is a Vocaloid staple, and this version leans all the way into the candy-and-costume chaos of the season.
A Vocaloid Halloween Classic Gets the Mabo Dofu Treatment
Let’s talk about the source material for a second, because it matters. Happy Halloween was written by Junky and originally sung by Kagamine Rin (鏡音リン), and it’s become one of those songs that resurfaces every October like clockwork — catchy, hyper, and impossible not to hum once it lodges in your head. Mabo Dofu mentions in the video description that this is a favorite they’ve found themselves humming every time Halloween rolls around, and you can hear that familiarity in the performance. Nothing about this feels like a song being read off a page.
The nqrse Rap Section Gives This Cover Its Own Flavor
The interesting wrinkle here is that this isn’t a straight copy of the original — the rap lyrics come from nqrse (なるせ), the rapper and lyricist known for their own wildly popular cover lineage of this exact song. Folding that rap section in gives Mabo Dofu room to switch gears mid-track, moving from the bouncy melodic hook into a rapid-fire passage that keeps the whole thing moving. It’s a smart choice: the original is beloved, so the cover needed something of its own, and this is it.
Spooky-Cute Production From a Small but Sharp Team
The instrumental and mix come from mikulu.copy (みくる.copy), keeping things bright and bouncy where the song needs it. The visuals match the energy — Raina handles the illustration while chOTaro puts the movie together, and the whole package leans into that dreamy, sugar-rush Halloween vibe Mabo Dofu describes loving in the description. Three hundred–plus likes on a cover sitting at just over 1,300 views is a striking like-to-view ratio, too — the people who found this clearly really found it.
Why This Happy Halloween Cover Lands
Seasonal covers are a crowded field every October, and the bar for a Happy Halloween cover is genuinely high because the original is so entrenched. What makes Mabo Dofu’s take work is the enthusiasm — this reads (and sounds) like a fan performing a favorite, not a performer checking a seasonal box. If you want something fun and unpretentious for your Halloween playlist, this is an easy add.
