Can't remember the name of a smile on desktop.

Recently I remember that I use one software (like a widget of KDE) in past on a preview versions of GNU/Linux systems around 2014 or something like that. I use some systems with a software aplication to desktop decoration that consists on asmile face that stay on desktop. Is similar to bouncy ball of KDE but is a smile face.
Is a enhancement for desktop decoration but I cant remember the name and I search around internet and cant find nothing and in synaptic I cant find the software.

Anyone remember the name of this widget or something like it ?

Thanks.
