Thought I'd give this fad a bit of a try myself. 
Replaces all the sound effects for Vyper's Lethal Venom with sounds (mostly) associated with the Roaring Knight from Deltarune. I'm a bit of a sound design nerd, so I got carried away.

Cast sound is the UTDR knife slash sound, plus FRIEND's laugh (which the Knight technically uses!) and a whooshing sound from Chapter 3. The LP before the venom detonates is Breath, ripped from the game's "mus" folder. The different sounds for the venom detonating is different sounds from the Knight teleporting/slashing, with the boxslash ambience played at different speeds over it. I also tried and failed to recreate the "SWOON" impact frame sound effect to layer it in the back of the strong variation.
