Scratch

Hello welcome to scratch have fun scripting and don't be afraid to ask questions, you can do it and it is quite simple.
Add these to the sprite you want clicked

when gf clicked
set [hiding v] to [0]
show

when [sprite 1] clicked
if <(hiding)=[0]>
set [hiding v] to [1]//any variable which only contains 0's and 1's mean 0 off 1 on
else
set [hiding v] to [0]
end

when gf clicked
forever
if <(hiding)=[1]>
hide
else
show
end

Duh! Easy!

Here ya go! Add this one on the menu button:

when (menubutton) clicked
broadcast <hide>

And put this script on the ones you want to hide.

when I receive <hide>
hide

No offense, but the 'Duh' sounded a bit rude...
