Explainer toolkit - looking for a specific product

Hello Community :slightly_smiling_face:
I’ve searched many products on “Explainer toolkits” for After effects but I’m looking for a specific product, I’m hoping it’s an “After Effects” plugin. I only have the visuals… I really need the name of the product that has these visuals and the characters… please help!
