dr. hippo's got a weird pear shape that's perfect for Lucrecia to grab the spikey ball side by and for me to hold the upper half while tugging :) she tugs and thrashes a LOT, and she loves doing it with dr. hippo. the spikey ball has a squeaker that sounds higher pitched than her other babies and for some reason that's an appeal to her lol. i swear i think she chooses the most obnoxious-sounding toys on purpose, she's too smart NOT to... this toy's also got kind of a wacky bounce unlike a lot of the other fabric toys she has, so she loves chasing after this one a lot. surprisingly, Lucrecia has not attempted to tear her up; she usually does not hesitate to do so with fabric toys.. sometimes when i get a toy for my corgi, i worry it might be a little too big or a little too small- dr. hippo is a perfect size for my medium-sized baby!
