Birthday gift ideas for 5 yo twin boys?

[TwoBees]

DD2 is invited to the birthday party of a classmate and his twin brother. I have no idea what to get other than Legos. Suggestions? And if I get Legos, do boys that age prefer the Juniors, or should I look for the regular sets that have an age range starting at age 6?

I would do regular lego sets from Target with a gift receipt.

I'd get the Junior set of Legos. DD2 is in that range between the two types of sets and the smaller pieces in the regular sets can get very frustrating. She's great at putting them together, but the teeny tiny pieces are just hard to get on right for little hands. But, yes to the gift receipt.
