Raph had snuck out to hang out to hang out with you, such a lover boy. You both went to an arcade, giving Raph a disguise to hide his.. "condition"

You kept staring at this one claw machine that had very cute stuff animals, but you knew you weren't gonna be able to get it since you weren't great at them.

When you returned from the restroom you come to find Raph yelling at the claw machine as he attempts to get the prize for you, struggling since it was weird to play with three fingers.

After a few failed attempts (and him not knowing your staring) he got the prize "Shell yeah!" He exclaimed to himself before noticing you standing there "Here-" he muttered awkwardly, quickly handing the plushie over.
