This egg was only given out on February 13 and 15 of 2010. It reappeared for its 10 year anniversary for the Chocotravaganza Exchange in 2020.
Tine are a magical love creature that make Valentine's Day in Ark very exciting and unpredictable. If the slightest amount of fur from their heart-shaped tails rub up against you (which is virtually impossible to avoid if you have one), you'll instantly fall in love. The bad part is you do not have control who you fall in love with. Thankfully, their magical power only works on February 13 and 14 and wears off as soon as the clock hits midnight.
