Most buns will pick respective places to recline in when they are contented fluffs. Some typical bunny resting poses are as follows:
The loaf or bun cake
And the crescent
Resting buns often enjoy head rests, be it a hard edge
or another contented fluff
Some also opt for the positions super bun
or dead bun (not actually dead)
If your bun achieves this stage, you indeed have a very contented fluff.
