The way I got this achievement was to throw cans of Grob on the heads of Pufferbirds and have them charge at me until they killed me. At the time, I also had a few extra health bars from eating the orange goo, so I jumped off of some high places to reduce my health a bit to speed up the process.
This can easily be done at the start of the game in the caves just outside the Javelin since you only have 3 health bars. Otherwise, just venture out a bit further.
I'm not sure if this is important or not, so I'll mention it anyways; the death animation you're looking for is you falling to the ground and the screen "cracks" in a few places. Once you respawn, simply walk back to the area you died, press
on the d-pad, and hold
to scan your corpse.
