The ATMEGA640-16AU is a high-performance, low-power 8-bit AVR RISC-based Microcontroller combines 4kb EEPROM, 86 general purpose I/O lines, 32 general purpose working registers, real time counter, six flexible timer/counters with compare modes, PWM, 4 USARTs, byte oriented 2-wire serial interface, 16-channel 10-bit A/D converter and a JTAG interface for on-chip debugging. The device achieves a throughput of 16 MIPS at 16MHz and operates between 2.7 to 5.5V. By executing powerful instructions in a single clock cycle, the device achieves a throughput approaching 1 MIPS per MHz, balancing power consumption and processing speed.

Adorable but not Durable
Color: Blue
While this toy was super adorable and our 1 year old puppy loved it. The colors were bright and vivid, and it made fun wrinkling sounds he absolutely loved.
However we were lucky if it lasted 20 minutes. Within minutes the crinkle paper was coming out and it basically fell apart, and he's not a destructive pup.

It’s been several months and all 3 still intact!
I have to be very selective because MOST toys labled recommended for “aggressive chewer” last about 20 minutes. Not kidding. These are the real deal. I’ve had these for several months now and all 3 are shockingly still completely intact and look like they did the day I got them.

Great option
Got this pack of toys for my new Great Dane puppy. He is in a very intense chewing phase and so far these are holding up. He loves that they squeak, and make a crinkly noise in the legs. I love that there is no stuffing to clean up if he manages to get it open. They way the arms move and flail really makes him love these toys. Will buy again when he needs new ones.

Great buy! My dogs love e them
My dogs love these things but don't last long with my crew. They aren't meant for aggressive chewers. Which mine are but I still buy them because my dogs love playing with them. I have one dog who is a pro at removing squeaky within 5 secs , no lie she's mastered it.
Def do not leave your dog unattended. I immediately take the removed squeaky and toss it. My other dog gets the crinkle plastic out whi h I also throw away. They still play with them. I toss them when they are torn to shreds and replace them. My dogs are picky on which toys they like to play with. Which is why I keep buying them.
