You can get these themed stickers from the Play Store and choose from a variety of options.
All you need to do is search for Onam WhatsApp stickers on the Play Store. A list of apps will pop up on the screen, you can choose and install the preferred apps. After they are installed, open the app and select the stickers that you want to use and tap on the "+" icon, then press "Yes" when "Add to WhatsApp" is prompted.
That's it, now you open the WhatsApp chat and fire away with the stickers.
