[TOMT] This older Netflix cartoon around 2016 (action, comedy)

I used to watch this show where there were these characters who fought monster like enemies and were trying to survive. It had CGI animation, and a distinct animation style. The characters kinda reminded me of castle crashers. I watched it on my wii with my sister when I was younger. I only remember one part distinctively. There is a scene where they are visiting a theater, (outside). One or two of the characters are looking through a box of props. and a knuckles like character (sonic) picked up a skull and referenced Shakespeare. "to be or not to be, that is the problem" He then got corrected because he said it wrong. I am 100% sure that scene exists because we had a skull decor and my sister, who was very young, picked it up and recited the same thing (wrong)

Any help would be valued, and any further questions I will try to answer
