The blind-boxed BetXO series from BIC Plastics includes pairs of 2″
stackable animals with an interchangeable top figure. The line consists of twelve
figures in all: six top animals (Mouse, Eagle, Lion, Rabbit, Monkey and
Kangaroo) and six base animals (Dog, Elephant, Pig, Hippo, Bear and
White Bear). One animal has no arms (base)...one has no legs (top) so the bottom animal
carries around his friend in a backpack. I like...two thumbs up!
