I need some ideas for playtimes with little Sushi- He is getting bored of the 'ol grab-the-toy-and-I'll-chase-you games. Currently, it is snowy and cold out so inside ideas would be preferred but outside ideas are OK too. Sushi loves the snow and has a coat so temperature is not an issue but I don't want him getting too cold. Sushi doesn't like tug-of-war and I'd like something that tuckers him out after so we can cuddle

Oh, and it's his half birthday (6 months!) so he will be eating a big treat, if that affects things. Thanks in advance.
