Hard-to-Find Items and Stuck Spots
Sometimes Lost and Found Co. is not testing whether you understand the clue. It is testing whether you are willing to believe one tiny object really is hiding in that awful little corner. These are the stuck points that waste the most time because the item blends into props, needs one extra interaction, or used to be tangled up with an old patch issue.

Missing Meow: the last wallet
The wallet that burns the most time is inside the yellow-and-white tube. Click the tube until it rolls fully clear, then open the cap and check the inside. If you are still missing one after that, re-check the pillows below the cat lady painting because another wallet can blend into the bedding and look like part of the pattern.
Missing Meow: the last mouse toy
One mouse toy likes to disappear in the cat condo area. Search the middle room around the lower-left mouse-hole area near the large cat tower and the stacked boxes. If the hole is not open yet, trigger the crystal-ball interaction with the angel cat first. After that, check the dark rafters too, because the toy can read like part of the woodwork.

Tea Time Troubles: daifaku
The daifaku is easy to skip because it blends into the pink flower display. Search beside the laughing couple and click around the flower vase edge, not just the open table space. If you are staring at that section and thinking the dessert must already be part of the scenery, that is exactly why this one gets missed.
Talk to Mallet objective not progressing
If the game tells you to talk to Mallet and he does not seem to exist, check your version before doing anything else. Patch 1.0.5 fixed the softlock that could happen if you earned enough popularity points before that sidequest properly unlocked. In normal play, Mallet's own extra hint points to the area in front of the office after the smoothie showdown, so search there once your build is current.
Last-object cleanup rule that solves more problems than it should
When you are missing exactly one thing, stop doing full-room laps. Re-read the task, pick one prop cluster that matches the clue, and interact with every layered object in that cluster before moving on. Tubes roll. Caps open. Hidden holes appear after the right event. In this game, one extra click is often the real answer.
