My two boys are all in to monsters, zombies and fast cars at the moment. With Monster 500 toys they get a little of all three at the same time. What are Monster 500 toys you ask? Monster 500 is a line of toys including small monster vehicles, large monster vehicles and monster 500 play sets like the graveyard gauntlet track set and the toxic terror trap set.

Monster 500 is a unique line of highly collectible, wonderfully fiendish monster characters driving small and large vehicles, plus two fabulously freaky play sets. The characters marry a child’s love of cars with the ghoulish and gross—the perfect combo! Each vehicle aligns with the Monster 500 app, which allows fans to bring their favorite monster characters to life in an action-packed racing game.

The boys and I put together the Toxic Terror set first. We followed the photo only step by step instructions and found it to be a tad confusing at first but figured it out after a couple minutes of studying each part of the set. This particular set sells for $34.99. You'll need 3 AA batteries (not included in the set) for the sound effects of this set. Both boys laughed as they let their monster cars loose on the elevator down the spiral track wondering if the car will get by the toxic monster and through the gate or will they be eaten by the mutant gator.

After playing with the Toxic Terror set a while the boys wanted to try out the Graveyard Gauntlet track set. This set was very easy to put together with the instructions. The Monster 500 graveyard gauntlet sells for $19.99 and no batteries required. You need a table to attach the start of the race track to and then you run the double track out and add the swinging pendulum to see who will raise the checkered flag in their lane and make the skeleton eyes pop out. I enjoyed watching the boys race and they had fun taking turns swinging the pendulum to see who's car would escape and who would win.

There are 4 large vehicles: Zoom Zombie, Flattop Frank, Crocpot and Lead Foot. These vehicles are much too big for the track play sets but because they have battery operated sounds the two boys had fun running the Flattop Frank car around the house (and pestering the dogs).

There are 10 small Monster 500 vehicles. You can get the small vehicles in single or triple packs. The singles are $4.99 each and the 3 pack is $14.99. All of these small vehicles can be used on the 2 play sets and you can use the codes found on cards in the vehicle packaging that unlock cars on the Monster 500 racing app game.

The boys have enjoyed playing with all of their Monster 500 toys and have asked me to find the remaining small cars for the play sets.

You can find the Monster 500 app for free in the App store or Google play. You can also find Monster 500 on twitter and Facebook.
