i have been looking online etc and they say its located either in data/local or system/media but i didnt see the bootanimation file in either of those places
In your mom, the first "Team Hydro Presents" boot is baked into the boot.img. That's going to be a task and a half to get in there and mod those. The second "android" boot you see is the stock bootanimation baked into framework-res. Also a bit of a chore to mod.
If you can find a bootanimation you like create a folder in data named local and place the boot there. Then reboot.
