These limited edition collectable Pokemon cards will only be available for a limited time. Adult collectors are swooping them up in a hurry.

For a very limited time, McDonald's is giving out special booster packs of Pokemon cards. While they're intended for kids, adult collectors can't keep their hands off of them. The giveaway is in celebration of Pokemon's 25th anniversary. Each pack comes with four cards, and there are 50 total in the collection.

If you're worried about not getting an opportunity to score some, remember that this ain't McDonald's first rodeo.

"With such significant demand for our promotional Pokémon TCG cards, and some fans even going to extreme lengths to get them, we're working quickly to address shortages and also strongly encouraging restaurants to set a reasonable limit on Happy Meals sold per customer. We want to offer the full Happy Meal experience to as many families as possible, and help ensure everyone is able to get in on the fun!"

Some are saying they haven't seen this kind of buzz for a Happy Meal toy since the Beanie babies in the 90s.

Some collectors have been sharing photos on social media of whole cases of cards they've purchased. McDonald's policy is that all Happy Meal toys are intended to be sold with the meal. Some locations have honored reasonable requests for purchasing additional packs, but McDonald's prohibits the sale of entire cases.
