See Inside and backpack the 3 blocks provided if you want to use.
Was bored again so I decided making 5 Scratch 3 blocks and share it. By the way, t̶h̶e̶ ̶S̶c̶r̶a̶t̶c̶h̶ ̶c̶a̶t̶ ̶i̶s̶ ̶a̶l̶s̶o̶ ̶t̶r̶a̶c̶e̶d̶ ̶f̶r̶o̶m̶ ̶t̶h̶e̶ ̶3̶.̶0̶ ̶n̶e̶w̶ ̶o̶n̶e̶ EDIT: Actually found the Scratch 3 cat SVG and imported it now. You can use the custom blocks if you want. UPDATE: Added layer blocks. Those blocks use broadcasts to show 'front, back, backward and forward'. Highly recommended to drag the sprite into your backpack rather than drag the scripts onto it to avoid losing the broadcasts.
