Answer: Bawl/Topper

In both the intro and after collecting 75 Jiggies, when playing in Spiral Mountain, Bawls appear hopping around. In one of the Jinjo Challenges a Jinjo asks you to find a Topper and bring it back to him.

Answer: High Grip Wheels

You get the High Grip Wheels from Nutty Acres Act 3, they allow you to drive up the green low-traction slopes.

You get the Floaters from Logbox 720 Act 3, they allow you to float in the water.

You get the Scuba Seat from Jiggoseum Act 4, it allows you to go underwater without needing air.

You get the Laser from Jiggoseum Act 5, it allows you to break laser gates.

Out of them all, including the ones not as answers in this question, the High Grip Wheels are the most important because you can't access much more than the Town Square without them.

Answer: Cow

In Nutty Acres, there is a large gear at the very top of the map. If you use a flying vehicle to get up to it, there is a cow. It is possible to make the cow fall off.

Answer: "Space Invaders"

In one challenge in the Logbox, you have to destroy these bugs with a "bug zapper". They are very similar to "Space Invaders" from the game with the same title.

Answer: "Grabbed by the Ghoulies" cases

If you look inside the trash bin of Banjoland, you will find multiple "Grabbed by the Ghoulies" cases inside. This is a reference to "Grabbed by the Ghoulies" being a large commercial failure. Other items are also found outside the trash bin, including gum.

Answer: "Chinker Freezers 26"

Chinkers are enemies from "Banjo-Kazooie" for the N64. However, the scoreboard never reads a team related to them. The scoreboard will say "Is anyone even reading this? If..." after you've been watching it for a while. "Twycross Athletic" is a reference to where Rare is situated.

Answer: Yes, in the challenge "The Saucer of Peril Returns".

In "The Saucer of Peril Returns", you have to shoot targets while situated inside the Saucer of Peril, which Boggy is piloting. Eventually, you will have to shoot targets inside the space outside the Terrarium. The airlock force-field gate isn't the same as the Showdown Town Laser Gates. The glass is unbreakable.

Answer: She instantly dies, then the game ends.

"Hero Klungo Sssavesss Teh World" is a minigame playable from Klungo's Arcade at the pier. In the final level, you simply have to jump over a fireball a witch throws at you. If you manage to, then the witch (oddly enough) instantly dies.

Answer: Three

In the Test-O-Track, there are three soccer balls. One of them is in the center of the racetrack area. The next is floating in the middle of the pool. The last one is floating directly above the first one.

Answer: Sticky Ball

To get this achievement, you need to get the floating soccer ball into a tube in the Test-O-Track. The spring is simply useless for this. The ball automatically reverts back to its original height if its pushed down or up, making it impossible to carry with the Large Tray.

The Floater is used to float in water, even if that part goes in the tube, you won't get the achievement. If you use the sticky ball, you can stick it and carry it around, and move it from its standard height.
