in the episode as one of his "greatest moments", noting, "how could we have missed that Takei did the voice for this sleazy science-talking heart on Adventure Time, our new favorite show?" Tyler Foster of DVD Talk called Ricardio one of the highlights of the season. The A.V. Club reviewer Oliver Sava, in a review for "Lady & Peebles", wrote that Ricardio is "always welcome on this series, largely due to Takei’s delightful voice work." Furthermore, he praised the way that Takei delivered his lines, noting that "there’s a theatrical smarminess to his vocals that is a stark contrast to the Ice King’s nasality", and that "Takei always sounds like he’s having a great time reading the ridiculous lines that are written for him."
