I'm Not Very Nice

"I'm Not Very Nice" is a music video featuring Hildy with Grim. First announced at the 2016 San Diego Comic-Con, it premiered with the series finale episode "A Royal Pain in the Castle" and "A Sneeze in Time" on November 5, 2016. Prior to its release, a similar, simplified variation of this song can be heard in "Hildyrella".

Lyrics
Hildy: Na, na, na, na, na, na, na Na, na, na, na, na, na, na Na, na, na, na, na, na, na I'm not very nice

Some girls, they like being helpful They call their grandmas every night But I'm not one of those girls I'm not very nice

Some girls don't like making faces Their brothers know they never fight But I'm not one of those girls I'm not very nice

Though I tried it for a while Said thank you with a smile But it just was not my style Some girls are kitty cats But I'm a crocodile

Na, na, na, na, na, na, na Na, na, na, na, na, na, na Na, na, na, na, na, na, na I'm not very nice

Some girls, they like being gracious Some girls always act polite No, I'm not one of those girls I'm not very nice Grim: (She's not!)

Hildy: Some girls do what their parents tell them Who never have to ask them twice Oh, I'm not one of those girls I'm not very nice Grim: (I should know!)

Hildy: I know I've never been delightful like a queen That just isn't my scene You know, now that I think about it I'm really actually kind of mean Grim: (Yeah you are)

(Instrumental Bridge)

Hildy: Some girls, they are sweet as candy Always sugar, always spice But I'm not one of those girls I'm not very nice

Some girls always do their homework Some girls always sit up right Oh, I'm not one of those girls I'm not very nice (Now!)

Hildy: Na, na, na, na, na, na, na Na, na, na, na, na, na, na Na, na, na, na, na, na, na I'm not very nice Grim: (No she isn't!)

Hildy: I'm not very nice Grim: (Not at all!) Hildy: I'm not very nice Grim: (She's really kind of scary) Hildy: I'm not very nice (Ha!)

Simplified Variation Lyrics
As heard in "Hildyrella" Parry: Na, na, na, na, na, na, na Na, na, na, na, na, na, na She's not very nice Hildy: (Dancing and magic at the same time! Am I blowing your mind or what?) (Woah, Ah!) Parry: She's not very nice Happy: (The Queen's skates!) Hildy: (Wait, hold on!) Parry: Na, na, na, na, na, na, na She's not very nice
