So i'm currently working on recreating the Undertale Froggit fight in scratch, and want to do other fights after it is done. But I am worried about how i'm going to get the sprites for future fights, because I don't know how to do that. So if anyone knows a way to access Undertale images, please let me know.
(I have looked on google for photos of certain sprites and can't find the one I need)

Which one do you need? (What character?)

(Edit: I am not at all familiar with Undertale so I will need the images and I can get you a picture.)

There is a certain attack froggit will do a frog spawns in the box, and then jumps towards you. I don't have either the sprite of it on the ground, or the sprite for it jumping, and am having difficulty finding it online
