hehehe... my piggy has a short tunnel she loves to 'hide' in. the husband and i laugh at it because she has her fluffy rear end sticking right out! occasionally when we feel mean we'd gently prod her little butt XD
Mine always leave their behinds sticking out of the pigloos. It cracks me up though because THEY CAN still see me! But then when I reach down and touch their butt they turn around and look at me like "how'd you find me Mom?!"
