My parents have this fabulous big blue ball. It has a really weird texture as it is covered in many soft blue strands that feel sort of like odd hair all over. To make things even more interesting there is a light inside that lights up when you shake it. This has become our official "tickle ball." It is largely self-explanatory, but a great time. Here are some shots of B as the tickle monster.
That said, B has become quite the tickler in general. It may have started long ago with Grammy's feet (one of his favorite targets still). Now, he tickles me to "wake me up" after he has instructed me to go to sleep. He tickles baby sister, daddy, uncle able and really anyone who will come within tickle range when he's in one of his tickler moods. Sometimes he gets a little aggressive, but mostly it is just completely adorable to see the little mischievous grin on his face as he prepares for his next victim. Just love it!
