I dont understand why im getting a nil value with clone?

I don't understand at all why I'm getting a nil value with "Clone"?

Please someone help me I don't understand one bit why this is happening

INFO: I have a folder in ReplicatedStorage called "Pets", All of my pets go inside there

INFO: I have a remote event inside ReplicatedStorage as well called HatchEgg than i have leaderstats connect to this all.

I have a Module script inside ServerScriptService than i have a model with a ClickDetector that has a Script (Not a localscript) inside that model than on top of that i have a localscript inside StarterGui

Error code:
