Can I get the Boing tone back for text notifications on iPhone?

I’ve had the “boing” text tone for over 10 years. I accidentally toggled off the tone and now it’s missing entirely. I just found the“boing” tone under ringtones. What’s going on and how do i get it back to text tones? The other text tones aren’t as loud as boing and they sound like android tones. I hate them!
