Hey HappyMasky! I'm Technobliterator, and I'm the Fandom Wiki Manager for Scribblenauts Wiki. I'm here to help your community, and I'm a liaison to full-time Fandom Staff. If you have any questions relating to the wiki, whether it's code-related, policy related, or otherwise, I'm your first point of contact.
Feel free to let me know if you need anything! I'll check your RecentChanges every so often, but for the quickest replies, drop me a message on my talk page here!
Do you mean gifs? I use this website https://ezgif.com/maker. To extract the frames from the gif, I use Gif Viewer (I don't remember where I downloaded it from...). And to make the background transparent I use paint.net.
