oh my god i never noticed that
i need to play undertale to find more stuff like this brb

And when mettaton turns into his non box form the music that plays while it's still a silhouette sounds awfully like the music that's plays when Susie in deltarune pushes you against the locker

I found another reference so rn I'm fighting mettaton

So he calls his show "attack of the killer robot)
Referencing "attack of the killer queen" in deltarune
If you think about it mettaton and queen aren't that different

This is why toby is the best dev ever thooo
so many hints and stuff. I dont even want to get into the comedy and the fun values-
I can't wait for the first newsletter thing to come in aaaaaa

Apparently there's a lot of hints to deltarune in Undertale and if I remember correctly Toby fox was thinking of deltarune before he made Undertale so that's cool
