When powered gimmicks like lights or sound are part of a toy, designers must solve how to make the batteries accessible without compromising the external aesthetics of the product, or the internal structure requirements. Commonly a hatch is placed underneath, or at least on the rear face that wouldn’t be seen as often. Some solutions are more successful than others.

3.75" figure scale TARDIS by Character Options

Can you spot the battery cover?

Here on this TARDIS (scaled for 3.75″ figures) I actually don’t mind the screw head nor the finger indentation to make prying the cover off easier. I only wish the hatch seams lined up more with the indented panels of the surface. It adds a lot of unnecessary lines. Why not put the hatch at the bottom? Because the toy has a non-powered gimmick of being able to spin like a top (just like on TV!) on a pivot underneath while twirling the top lantern by hand.

It’s the kind of detail that die-hard toy collectors must accommodate, if a little unwillingly, in order to have their favorite vehicle. Let’s face it, toys are meant to make money aimed at kids, not adults who are kids at heart.
