The It’s Showtime! II lasagna locations in Garfield – Escape from Monday work differently from most of the collectibles you have encountered so far.
The level is split into three waves, and each wave opens a different section of the stage. Every section contains one lasagna.
The important part is timing. Once you advance to the next wave, the previous section can become inaccessible for the remainder of that run. That means you should always collect the current lasagna before triggering the next wave.
All It’s Showtime! II Lasagna Locations
There are three lasagnas in It’s Showtime! II, with one assigned to each wave.
Lasagna Location #1

At the beginning of the level, ride the platform downward and continue until Chef Monday appears.
You will then need to step into a spotlight, which starts Wave 1/3.
Once the wave begins, head straight into the newly available section.
The first lasagna is floating above the path.
Use the rising platform to reach it and collect it before doing anything that starts Wave 2.
If you advance to the second wave without grabbing this lasagna, you cannot return to it during the same run.
Lasagna Location #2

When Wave 2/3 begins, the curtain beside the right-pointing arrow opens.
Head through that curtain and follow the new path.
Continue through the entire section and you will reach the second It’s Showtime! II lasagna at the end.
Collect it before triggering Wave 3.
Just like the first collectible, the route will no longer be available once the next wave begins.
Lasagna Location #3

After starting Wave 3/3, the curtain beside the left-pointing arrow opens.
Follow the path behind it.
The third and final lasagna waits at the end of this section.
Make sure you collect it before completing the wave and finishing the level.
What Happens if You Miss a Wave Lasagna?
You cannot return to an earlier wave during the same playthrough once the next section has started.
However, you do not lose the lasagnas you already collected.
After finishing the level, return through Dreamland and replay the stage. Previously collected lasagnas remain saved, so you only need to grab whichever wave collectible you missed.
You also do not need to repeat every cheese collectible during the cleanup run.
