The Kragle, in case you’re the one person who hasn’t seen The Lego Movie, is the “superweapon” that evil villain Lord Business uses to try to freeze the world into “perfection.” In the end, (spoiler alert) the Kragle is revealed to be Krazy Glue and the hero caps the bottle/weapon so the world isn’t frozen into place and new designs can be created.
The first 50 times my kids watched this movie, I had no problem thinking that gluing Legos was evil. But sometime after my youngest child turned three and became OBSESSED with Legos, I had a change of heart.

My son loves Legos so much it’s only a matter of days, sometimes minutes, before he breaks them. I don’t blame him. Sometimes Lego Batman’s car needs to be smashed into Lego Darth Vader’s tie fighter to save the world. But I’ve found that to save my sanity, sometimes you need to glue Legos together with “The Kragle” so they don’t break so easily.

You can be a good guy and glue Legos too. In fact, you need to glue Legos to be a good guy. Embrace The Kragle.
10 Good Reasons the Lego Movie’s Kragle Isn’t Only for Bad Guys
- It’s impossible (for normal people like me) to remember how to build anything. Yes, every set comes with instructions and I usually keep them, somewhere. But those instructions could be anywhere in my house – most likely in the last place I will look. And I don’t have the memory to build a Lego set again without instructions. Too many toddler kicks to the head.
- Lego sets are too specialized to rebuild without instructions. Legos are awesome because you can build such cool things with tremendous detail. But if a set is destroyed, the leftover pieces are so specialized that it’s hard to build anything that looks normal.
- The Kragle lengthens the life of a parent’s back. More Legos spread across the floor means more Legos spread across the floor for parent’s to bend over and pick up. If kids want their parents to keep carrying them or playing in the backyard, they should want their parents to pick up fewer Legos and spare them the wear and tear on their backs.
- The Kragle saves money. When Lego sets break apart, as they always do in the hands of children, my kids want new sets to replace the old. But Lego sets are expensive. So if we want to have money for food, it’s best if Lego sets are reinforced with glue.
- Complete sets are more fun. Kids may enjoy breaking Lego sets, but once they’re broken the fun is over. So kids should want the help of glue to keep their Legos together.
- Legos glued together are harder to lose. My kids can lose a shoe they are wearing, so it’s safe to say that if a piece falls off of a Lego set, it’s going to be lost and probably never found again. But if pieces are glued together, they will be harder to lose and easier to be found.
- If you want to be creative and build your own designs, you can buy a box of classic Lego blocks. Just because you glue sets together doesn’t mean you can’t create your own Lego designs. Buy a box of classic Legos. They’re much easier to work with than specialized pieces and less expensive than a set based on a popular movie.
- A completed Lego set is like a trophy. Lego sets might be fun to build, but they take time and work, sometimes more work than your kid put into getting their tee-ball trophy. So you should be proud of your work and treat it like a trophy your kid can play with.
- It’s not wrong to strive for perfection. It’s possible to strive for perfection like Lord Business wanted while still encouraging our kids to be creative. Like I mentioned, you can always buy more classic Legos if you want to start from scratch. Plus, Legos may inspire a kid to be an architect someday and create things never imagined before. But if that kid becomes an architect, I think we can all agree that it would be best if their buildings don’t fall apart easily.
- Legos are about bonding, so why shouldn’t they be bonding too? Legos provide a great way for kids to bond with their parents, grandparents, friends, etc. So why should we deny Legos the chance to be bonded together to their match forever too?
