Thanks to EREN16 who prepared this theme.
Let's clone the repo and enter the folder:
git clone https://github.com/yucellmustafa/plymouth-linux /tmp/plymouth-linux && cd /tmp/plymouth-linux
Copy the selected theme in plymouth theme dir:
sudo cp -r linux-penguin /usr/share/plymouth/themes/
# check if theme exist in dir
sudo plymouth-set-default-theme -l
# now set the theme (linux-penguin, in this case) and rebuilt the initrd
sudo plymouth-set-default-theme -R linux-penguin
# install the new theme (linux-penguin, in this case)
sudo update-alternatives --install /usr/share/plymouth/themes/default.plymouth default.plymouth /usr/share/plymouth/themes/angular/linux-penguin.plymouth 100
# select the theme to apply
sudo update-alternatives --config default.plymouth
#(select the number for installed theme, angular in this case)
# update initramfs
sudo update-initramfs -u
