How to Froggy Grind down the Helix Room | Foundry Pro Goals Challenge

Before we start with this Foundry challenge, you’ll first need to go into your Skater customization. Make sure to assign the Froggy Grind as one of your Special Tricks. After all, it’s obviously required for this challenge!

Once you load into the level, you’ll need to turn around as soon as you spawn. The entrance to the helix room is right behind you, it’s the circular room with the spiraling slope. That said, we also recommend filling up your Special meter first. You’ll need to have it full to pull off the Froggy Grind.

Inside the helix room, just skate all the way to the very top of the room. You’ll eventually reach a dead end, marked by a white and orange barrier as well as some traffic cones.

Then, from the barrier, turn around and jump onto the edge of the slope going down. Make sure to input whichever combination of buttons you picked for the Froggy Grind before landing so that you activate the proper trick.

All that’s left is for you to maintain balance and grind the slope all the way to the bottom. Make sure you don’t fall so that the trick doesn’t cancel out!
That’s all you need to know to complete the “Froggy Grind down the Helix Room” Pro Goal for the Foundry level in Tony Hawk Pro Skater 3+4. This might’ve been a Pro Goal, but it’s honestly easier than the regular Grind the Molten Bucket challenge…
