It really would be a bad time. But Themis has already sent Elecmon ahead and he's just going to have to make do. Let's be honest it's probably slightly more efficient than waiting for the Goblimon to become focused enough to make a big reveal.

Maybe. Probably.

Elecmon's plan was pretty simply and relatively harmless as her typical pranks would be. Making her way back to the entrance of the cargo car but not out of it. What she looks for first are vents or small spaces she might clamber into. But in the absence of these she can definitely work with all the stacks of cargo.

She begins with little noises. Scrabbles, metal or wooden or otherwise. Maybe unzippering a zipper if there's one available. Some of these sounds will be easily carried, others maybe not. But the point is that almost directly after she's done, Elecmon sneakily moves toward another position entirely, leaving a seemingly 'uninhabited spot'.

Operation Haunted Cargo Car has begun.
