You lil shit

Two animated characters stand behind a counter in a laboratory setting; the character on the left, wearing a bowtie, shifts from a surprised expression to a wide, excited grin, while the character on the right, wearing a hat, remains stoic. The scene cuts to a close-up of a third character with wide eyes and a tense expression, then to a close-up of his face showing an angry, gritted-teeth expression, before returning to a medium shot of him looking annoyed.
