Why does my boot loader(GRUB)graphic randomly change to penguins playing on ice.
First day of winter? (northern)
It’s built into the bootsplash image configuration. There is a switch to enable/disable it and an integer value to control how frequently it appears (or randomly). This link describes howto modify:

Doesn’t happen here (although I haven’t rebooted for a couple of days). Obviously good localisation: we have a few penguins in Oz but not too much ice for them…
