Weaners

 "pigpile" is a term people use for a group; this is the original pigpile.  These are weaned pigs in a pretty big pen, but when they sleep they get as close to each other as they can.   In the middle of the pile it's 3 pigs deep 

 They snore softly when they're sleeping; and they sleep really soundly.   If you clap or make a noise, all of the exposed ears flap in unison. 

 They stay pretty still when sleeping, but occasionally you'll hear some grumbling from someone in the pile.  Hey! 

 They are very cute.  This is the point of maximum pig  cuteness. 

 At the edges of the pile some pigs fall off, and there's some sleepy squealing as the pile rearranges itself, and then back to the snoring of the piglets.
