It’s different when it’s about Roblox made animations. You’ll have to use a specific plugin for them, called “Load Catalog Items” (Load Catalog Items - Roblox).
I’ll tell you the steps to implement them:
- Open up the plugin on Studio;
- Get the AnimationId of the animation that you want (in this case, i’ll get the run animation of the Werewolf bundle pack Werewolf Run - Roblox);
- Insert the AnimationId (in this case 1113750642) in the plugin’s textbox;
- Click “Insert”;
- In your workspace, you should find “Asset_YOURID” (YOURID replaced with the asset id of the animation you chose;
- Open up everything under that, till you find “RunAnim” (name will change based on the animation you got. If it’s the walk animation, then it’ll be named “WalkAnim”, of course);
- Now just copy the AnimationId of that and paste it into the animate script that @xxIamInevitable told you about and playtest the game.

There you go, Roblox’ animations usable in your game. Tell me if you didn’t understand something, and hope it helped.
