In the Lépine family, being a hedgehog is a family tradition... and a unique one at that. Because Bernard, unlike all his hedgehog friends, is strangely the only child in his litter. Finding this peculiarity difficult, he dreams of having a little brother with whom he can share his snails with apricot jam and pop balloons by jumping on them. But when the adorable little one finally arrives, Bernard's excitement turns to disappointment. After some thought, he decides he wants the little one back!
