Is this flowey from undertale?

I kind of found it in the wilds of the internet. I was scrolling past something when this image was just sitting there.

My mind tried to piece together it and then it went. "Yeah this is Flowey."

But I can't trust myself on IDing characters in the wild so I took a screenshot and showed it to a friend, who said "Yes this is Flowey."

But I didn't trust my friend on IDing characters in the wild so I've brought it here to these forums to get another set of eyes on this.

I know you only asked me where I found the image and I instead gave you my life story but I really want you to understand the utter turmoil I've been through because of this image!
