In this guide, you will find where to get the Toad Warts in Hogwarts Legacy. Go through the guide and follow all the instructions carefully to do so.
The first thing you will need to do is make your way to Giant Purple Toad Den at the northern edge of the map, near the North Ford Bog entrance.
Make sure to unlock the Nab sack for this and it is recommended to change the difficulty to story mode so that you can catch the Giant Purple Toad quickly. Head to the location using your broom and catch the beast using the nab sack.
After that, make your way back to Hogwarts and go to the room of requirement. Then head into any of your vivariums and put the beast in there, then you need to use your feed spell and the brush spell on the Giant Purple Toad.
