Board Thread:My Singing Monsters Forum/@comment-32643342-20170802121735

Rare Mammott is curently being offered in the Starshop. Does this mean it can be bred for free while the deal is going in the starshop. If not, I am just trying to find out when a rare monster can be bred for free. Is it only on weekends? Only when they are offered in the market? I have searched online but its all quite confusing with different answers.
