These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
The main theme from Thunder And Lightning Aren't So Frightening.
The theme from Lost & Found's "Bop a Prize" bonus game.
Point, one of the Group EF background music tracks from Life Is Rough When You Lose Your Stuff!
Fanon Discontinuity: Most fans out there like you to think that Life Is Rough When You Lose Your Stuff! never existed, to the point where they'll refuse to call it Pajama Sam 4.
Fridge Horror: Pajama Sam throws a plank of wood into the water to get Otto into the water, but when Otto and Pajama Sam look away the plank sinks. So that means that eventually Otto is going to sink.
Otto's a boat, so he's designed not to sink so easily, unlike a flat plank of wood. Still, it was horrifying for this troper at a young age.
Also, the Fridge Horror was likely unintentional; Sam is supposed to lose access to any items he has already used, so the plank's sinking was probably supposed to accomplish that, not show the player that Otto was going to eventually sink.
In Lost & Found, crashing into an obstacle causes his back end to sink.
If you don't want to scale the dresser, just have Sam fall down the first time you play the mini-game. From then on, Sam will be able to skip straight to the top of the dresser as if you had already completed the mini-game.
If you have completed the mini-game and can play it from the menu, playing it from there and having Sam fall down will warp Sam to the bottom of the dresser, regardless of where he was when you accessed the menu. This basically serves as a Warp Whistle (especially useful in a game with Loads and Loads of Loading), and even a Door To Before since it still works after the Point of No Return near the end of the game (allowing Sam to go back and pick up any trading cards he may have missed).
