A hole in a brick is called a frog sometimes. This is because often on job sites or ones who sat out for lengthy times on their sides frogs would decide to move into.
Well if a frog is on a brick even though it is in truth attached to a piece of rock, the frog doesn't change form, and is indeed, still a frog. creative question by the way.
I have just measured the diameter of a perforation of a three hole perforated brick(UK 1960's) it was 35mm diameter the brick itself was W102.5(approx') x L220x H75; I haven't got a v frog brick to measure single or double.

The reason for the recess in the surface of frogged bricks being called a frog is not known.A:One theory is that as the block used to press this indentation is also called a frog, possibly based on the appearance of this block especially if some clay adheres to it, and the name was transferred to the recess created in the brick by the frog.A:Another theory is that the similarity between the recess in a brick to the recess under a horse's hoof is the origin of the name "Frog".The compacted mud that drops out of a horse's hoof can look like a crouching frog or toad.

It's a frog.
The best method for filling a brick hole with brick hole filler is to first clean the hole of any debris, then apply the filler using a trowel, making sure to pack it tightly and level it with the surrounding bricks. Allow the filler to dry completely before finishing with a brush or sponge to match the texture of the surrounding bricks.
The power brick is at the very end of the level by the big hole before leaving though the hole at the back of the area to the right there is a small opening fly in it and you get the power brick!!

To securely attach a nail into a brick, you can use a masonry drill bit to create a hole in the brick, then insert a plastic anchor into the hole before hammering the nail into the anchor. This will provide a strong and secure attachment.
To effectively drill a hole in brick, use a masonry drill bit and a hammer drill. Mark the spot on the brick where you want to drill the hole, then slowly and steadily apply pressure while drilling. Make sure to wear safety goggles and gloves to protect yourself from debris.
