Yotsuba&!, Vol. 5

Yotsuba met a robot at Ena's house! Betcha haven't met one ever! It was
THIIIIIS big - but not bigger than Jumbo or anything - and it ate money!
Yotsuba's never met anyone who ate money before! Maybe it gets more
powers with more money!? Yotsuba should try giving it more money next
time! Huh...what happens when money-eating robots get full? Do they have
to go to the little robots' room? Hmmmm...
